The algorithm in formatTimezoneInfo\nwas manually checked that it works for negative fractional browser\ntimezones.\n\nformatDateRFC2882() from lib/datetime.js in this patch is roughly\nequivalent to dateOutputTZ() function from date.js in original patch\nby J.H. formatDateRFC2882() handles only +/-HHMM numerical timezones;\nknowledge about \"utc\" and \"local\" timezone settings is left out of\nthis function (but see localTimezoneInfo() function in this patch).\nformatDateRFC2882() explicitly uses padding (via padLeft()), something\nthat J.H. patch missed but was supposedly[*] fixed in Kevin Cernekee\npatch:\n\n Re: [PATCH 1/1] gitweb: javascript ability to adjust time based on timezone\n http://thread.gmane.org/gmane.comp.version-control.git/169384/focus=169891\n http://cache.gmane.org//gmane/comp/version-control/git/169891-001.bin\n\n[*] \"Supposedly\" only because I haven't bothered to check patch sent\n as base64-encoded application/octet-stream attachement.\n\n\nNOTE: tzRe was left as a global variable, as it was originally.

While\nKevin's patch changed the server side output so that the timezone\nwas output from gitweb itself, this has a number of drawbacks, in\nparticular with respect to gitweb-caching.\n\nThis patch takes the same basic goal, display the appropriate times in\na given common timezone, and implements it in JavaScript. This\nrequires adding / using a new class, \"datetime\", to be able to find\nelements to be adjusted from JavaScript. Appropriate dates are\nwrapped in a span with this class.\n\nTimezone to be used can be retrieved from \"gitweb_tz\" cookie, though\ncurrently there is no way to set / manipulate this cookie from gitweb;\nthis is left for later commit.\n\nValid timezones, currently, are: \"utc\", \"local\" (which means that\ntimezone is taken from browser), and \"+/-ZZZZ\" numeric timezone as in\nRFC-2822. Default timezone is \"local\" (currently not configurable,\nleft for later commit).\n\nFallback (should JavaScript not be enabled) is to treat dates as they\nhave been and display them, only, in UTC.\n\nPages affected:\n* 'summary' view, \"last change\" field (commit time from latest change)\n* 'log' view, author time\n* 'commit' and 'commitdiff' views, author/committer time\n* 'tag' view, tagger time\n\nBased-on-code-from: Kevin Cernekee \nSigned-off-by: John 'Warthog9' Hawley \nSigned-off-by: Jakub Narebski \n---\nThe only change from v2 is that we used\n\n epoch = parseRFC2822Date(curElement.innerHTML);\n\nnow we use\n\n epoch = parseRFC2822Date(curElement.firstChild.data);\n\nThis is because of two reasons:\n* it futureproofs fixDatetimeTZ() against eventual changes in\n structure of gitweb output (of contents of \"span.datetime\"),\n like e.g. timezone selection menu not deleted but only made\n invisible.\n\n* it is more consistent, because we have to use .firstChild.data\n instead of .innerHTML for setting, as the latter doesn't work\n for Mozilla 1.17.2 in [overly] strict settings (XHTML DOM +\n application/xml+xhtml mimetype). \n\n...\nThis is major part of J.H. patch.\n\nNOTE that while major ideas (and some of names) are taken from\nJ.H. patch, the code was practically written anew from scratch.\n\nI avoid using global variables, as recommended in various tips for\nbetter JavaScript performance. Global variables are discouraged\nanyway...\n\n\nActual interface for changing / selecting timezone is left for later\ncommit, both because smaller patches are easier to review, and because\ninterface part is more tricky and involves more issues\n\n...\nChanges compared to original patch by J.H.\n\n* In J.H. patch if the feature is enabled, i.e. if $jslocaltime is not\n equal '' (the check should probably be if $jslocaltime is false-ish;\n neither '-0000' nor '+0000' is false-ish), five additional SCRIPT\n elements are added: four loading new external scripts (libraries),\n one running onloadTZSetup()... and not as window.onload handler.\n\n This series makes it so gitweb.js is composed of newly introduced or\n result of splitting JavaScript files, so $gitweb_js remains only\n loaded external script (note: it can be minified). onloadTZSetup\n call is added to anonymous function which is used as window.onload\n handler. Thus there are no new SCRIPT elements.\n\n* The default timezone is 'local' like in J.H. patch, but it is passed\n from gitweb.perl as onloadTZSetup argument, and not put in global\n variable tzDefault from gitweb variable $jslocaltime (sic!). Note\n that in this patch default timezone is not yet configurable, and\n that you cannot yet turn off this feature.\n\n* The cookie name is 'gitweb_tz' not 'tzOffset', and is passed from\n gitweb.perl as parameter to onloadTZSetup, and not put in global\n variable named getwebCookieTZOffset (sic!).\n\n* The classname that marks dates for manipulation by adjusting\n timezone is \"datetime\" and not \"dtcommit\" like in J.H. patch,\n because of taggerdate ('tag' view) case. It is passed to JavaScript\n code as argument to onloadTZSetup().\n\n Note that thanks to next to previous patch we need to add \n '' only in one place: in format_timestamp_html\n function, as compared to J.H. patch modifying 3 places.\n\n* onloadTZSetup, which in this patch has options passed from gitweb by\n the way of function arguments rather than global variables, first\n checks cookie then fixes dates to given timezone; in J.H. patch it\n checks cookie last.\n\n In this patch we skip manipulating dates if timezone is 'utc',\n i.e. the same as gitweb already outputs.\n\n* original tzChangeNS -> tzChangeSNS (why this indirection?) finds\n elements by hardcoded classname \"dtcommit\" (though it might apply\n also to taggerdate), gets supposedly machine readable but not in all\n browsers (see Kevin comment in [1]) ISO-8601 format from title\n attribute, and uses it as base for datetime manipulation, and uses\n .innerHTML for changing output.\n\n fixDatetimeTZ finds elements with tzClassName class (passed down\n from call in gitweb.perl), uses original RFC-2822 formatted date\n from contents of the element (or rather its first child text node)\n as base for datetime manipulation, and uses .firstChild.data \n (W3C DOM 2 Core TextNode interface) for changing output.\n\n tzChangeSNS in J.H. patch also set cookie, and added triggers for\n timezone selection menu -- this really shouldn't be its job.\n\n The function to generate RFC-2822 date with adjusted timezone is\n named formatRFC2822Date and not dateOutputTZ.\n\n Please also take note of caching length of Array or live NodeSet in\n a loop.\n\n [1] http://thread.gmane.org/gmane.comp.version-control.git/169384/focus=169891\n\n* The knowledge of \"utc\" and \"local\" timezones is encapsulated in\n normalizeTimezoneInfo() function in lib/datetime.js, instead of\n being in dateOutputTZ(). Knowledge about how to get local timezone\n in +/-HHMM format is contained in localTimezoneInfo() function.\n\n gitweb/Makefile | 1 +\n gitweb/gitweb.perl | 11 +++++--\n gitweb/static/js/adjust-timezone.js | 60 +++++++++++++++++++++++++++++++++++\n gitweb/static/js/lib/datetime.js | 15 +++++++++\n 4 files changed, 84 insertions(+), 3 deletions(-)\n create mode 100644 gitweb/static/js/adjust-timezone.js\n\ndiff --git a/gitweb/Makefile b/gitweb/Makefile\nindex 7dd1dee..5d20515 100644\n--- a/gitweb/Makefile\n+++ b/gitweb/Makefile\n@@ -120,6 +120,7 @@ GITWEB_JSLIB_FILES += static/js/lib/common-lib.js\n GITWEB_JSLIB_FILES += static/js/lib/datetime.js\n GITWEB_JSLIB_FILES += static/js/lib/cookies.js\n GITWEB_JSLIB_FILES += static/js/javascript-detection.js\n+GITWEB_JSLIB_FILES += static/js/adjust-timezone.js\n GITWEB_JSLIB_FILES += static/js/blame_incremental.js\n \n \ndiff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl\nindex 67bcfe8..6651946 100755\n--- a/gitweb/gitweb.perl\n+++ b/gitweb/gitweb.perl\n@@ -3732,9 +3732,14 @@ sub git_footer_html {\n \t\t qq!startBlame(\"!. href(action=>\"blame_data\", -replay=>1) .qq!\",\\n!.\n \t\t qq! \"!. href() .qq!\");\\n!.\n \t\t qq!\\n!;\n-\t} elsif (gitweb_check_feature('javascript-actions')) {\n+\t} else {\n \t\tprint qq!\\n!;\n \t}\n \n@@ -3940,7 +3945,7 @@ sub git_print_section {\n \n sub format_timestamp_html {\n \tmy $date = shift;\n-\tmy $strtime = $date->{'rfc2822'};\n+\tmy $strtime = ''.$date->{'rfc2822'}.'';\n \n \tmy $localtime_format = '(%02d:%02d %s)';\n \tif ($date->{'hour_local'} < 6) {\ndiff --git a/gitweb/static/js/adjust-timezone.js b/gitweb/static/js/adjust-timezone.js\nnew file mode 100644\nindex 0000000..1577d78\n--- /dev/null\n+++ b/gitweb/static/js/adjust-timezone.js\n@@ -0,0 +1,60 @@\n+// Copyright (C) 2011, John 'Warthog9' Hawley \n+// 2011, Jakub Narebski \n+\n+/**\n+ * @fileOverview Manipulate dates in gitweb output, adjusting timezone\n+ * @license GPLv2 or later\n+ */\n+\n+/**\n+ * Get common timezone and adjust dates to use this common timezone.\n+ *\n+ * This function is called during onload event (added to window.onload).\n+ *\n+ * @param {String} tzDefault: default timezone, if there is no cookie\n+ * @param {String} tzCookieName: name of cookie to store timezone\n+ * @param {String} tzClassName: denotes elements with date to be adjusted\n+ */\n+function onloadTZSetup(tzDefault, tzCookieName, tzClassName) {\n+\tvar tzCookie = getCookie(tzCookieName);\n+\tvar tz = tzCookie ?

The\ncode is capable of handling fractional timezones, but those have not\nbeen added to the menu.\n\nAll changes are saved to a cookie, so page changes and closing /\nreopening browser retains the last known timezone setting used.\n\n[jn: Changed from innerHTML to DOM, moved to event delegation for\nonclick to trigger menu, added close button and cookie refreshing]\n\nHelped-by: Kevin Cernekee \nSigned-off-by: John 'Warthog9' Hawley \nSigned-off-by: Jakub Narebski \n---\nChanges from v2 version:\n~~~~~~~~~~~~~~~~~~~~~~~~\n* Removed setting of .onblur handler for timezone SELECT element, as\n this (probably) caused problems in Chromium / Google Chrome. Namely,\n timezone selection didn't work in (at least) Chromium 6.0.472.62 (59676)\n and Google Chrome 10.0.648.204:\n\n Uncaught Error: NOT_FOUND_ERR: DOM Exception 8\n removeChangeTZForm\n /gitweb-static/gitweb.js:785\n onTZFormChange\n\n line 785: var removed = container.removeChild(popup);\n\n Using debugger from Google Chrome I found that somehow container\n becomes DocumentFragment instead of 'span.datetime' element...\n\n Without this line (deleted in this patch from v2 version)\n\n select.onblur = closeTZFormHandler(documentFragment, tzClassName);\n\n in createChangeTZForm() function, just below setting select.onchange,\n it works correctly in those browsers.\n\n This change was send as\n\n [PATCHv3 10/11] gitweb.js: Add UI for selecting common timezone to display dates\n http://thread.gmane.org/gmane.comp.version-control.git/171600/focus=171632\n\n* Just in case we now use safer\n\n popup.parentNode.removeChild(popup);\n\n form rather than\n\n container.removeChild(popup);\n\n where somehow container === popup.parentNode assertion got broken in\n Chrome / Chromium.\n\n This recommendation comes from \"Professional JavaScript for Web\n Developers\" book by Nicholas C. Zakas.\n\n\nChanges from J.H. patch:\n~~~~~~~~~~~~~~~~~~~~~~~~\n* In J.H. patch to display timezone menu you had to click small \"+\"\n beside date, that was added for each date using JavaScript.\n\n In this patch to display timezone menu you have to click anywhere\n on date, as hinted by title='Click to change timezone' added to\n those elements via JavaScript, and link-like view on :hover\n via CSS added with JavaScript.\n\n* In J.H. patch clicking on \"+\" was handled with setting onclick for\n each such element:\n\n +\n\n once for each date (but only for 'log' view there are many dates).\n\n In this patch clicking on dates is handled via event delegation\n (event capturing for 'document').\n\n* In J.H. patch timezone menu was generated from scratch on each\n click on unopened \"+\" (which changed to \"-\" and handled closing)\n by setting target.innerHTML to string generated by concatenation.\n\n In this patch timezone menu is generated once on page load, and\n only attached on clicking on date. This menu is generated using\n DOM methods rather than innerHTML -- this is because my ancient\n browser (Mozilla 1.17.12 Gecko/20050923) considers innerHTML\n non-standard with strict mode (XHTML + application/xhtml+xml).\n\n* In J.H. patch to remove timezone menu without selection you had to\n click on \"-\" (turning it again into \"+\").\n\n In this patch to remove timezone menu you had to click '[x]' button\n marked with title='(click on this box to close)'.\n\n* In J.H. patch timezone menu was composed of table. In this patch it\n is simply
element.\n\n* Beside name of cookie, also cookie expiration time (in days) is\n passed from gitweb.perl down to JavaScript code by the way of\n onloadTZSetup argument(s).\n\nOn one hand side with current code is hopefully easier to understand\ncode flow. On the other hand it uses much more advanced features of\nJavaScript: DOM (mainly DOM HTML, with bits of CSS, Style and Core),\nevent delegation, closures, absolute positioning / visual model.\n\n gitweb/gitweb.perl | 3 +-\n gitweb/static/gitweb.css | 33 ++++\n gitweb/static/js/adjust-timezone.js | 298 +++++++++++++++++++++++++++++++++--\n gitweb/static/js/lib/common-lib.js | 27 +++-\n 4 files changed, 345 insertions(+), 16 deletions(-)\n\ndiff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl\nindex 6651946..b1e80ef 100755\n--- a/gitweb/gitweb.perl\n+++ b/gitweb/gitweb.perl\n@@ -3738,7 +3738,8 @@ sub git_footer_html {\n \t\t (gitweb_check_feature('javascript-actions') ?\n \t\t qq!\tfixLinks();\\n! : '').\n \t\t # last parameter to onloadTZSetup must be CSS class used by format_timestamp_html\n-\t\t qq!\tonloadTZSetup('local', 'gitweb_tz', 'datetime');\\n!.\n+\t\t qq!\tvar tz_cookie = { name: 'gitweb_tz', expires: 14, path: '/' };\\n!. # in days\n+\t\t qq!\tonloadTZSetup('local', tz_cookie, 'datetime');\\n!.\n \t\t qq!};\\n!.\n \t\t qq!\\n!;\n \t}\ndiff --git a/gitweb/static/gitweb.css b/gitweb/static/gitweb.css\nindex 79d7eeb..8dd0935 100644\n--- a/gitweb/static/gitweb.css\n+++ b/gitweb/static/gitweb.css\n@@ -579,6 +579,39 @@ div.remote {\n \tdisplay: inline-block;\n }\n \n+/* JavaScript-based timezone manipulation */\n+\n+.popup { /* timezone selection UI */\n+\tposition: absolute;\n+\t/* \"top: 0; right: 0;\" would be better, if not for bugs in browsers */\n+\ttop: 0; left: 0;\n+\tborder: 1px solid;\n+\tpadding: 2px;\n+\tbackground-color: #f0f0f0;\n+\tfont-style: normal;\n+\tcolor: #000000;\n+\tcursor: auto;\n+}\n+\n+.close-button { /* close timezone selection UI without selecting */\n+\t/* float doesn't work within absolutely positioned container,\n+\t * if width of container is not set explicitly */\n+\t/* float: right; */\n+\tposition: absolute;\n+\ttop: 0px; right: 0px;\n+\tborder: 1px solid green;\n+\tmargin: 1px 1px 1px 1px;\n+\tpadding-bottom: 2px;\n+\twidth: 12px;\n+\theight: 10px;\n+\tfont-size: 9px;\n+\tfont-weight: bold;\n+\ttext-align: center;\n+\tbackground-color: #fff0f0;\n+\tcursor: pointer;\n+}\n+\n+\n /* Style definition generated by highlight 2.4.5, http://www.andre-simon.de/ */\n \n /* Highlighting theme definition: */\ndiff --git a/gitweb/static/js/adjust-timezone.js b/gitweb/static/js/adjust-timezone.js\nindex 1577d78..0c67779 100644\n--- a/gitweb/static/js/adjust-timezone.js\n+++ b/gitweb/static/js/adjust-timezone.js\n@@ -7,34 +7,51 @@\n */\n \n /**\n- * Get common timezone and adjust dates to use this common timezone.\n+ * Get common timezone, add UI for changing timezones, and adjust\n+ * dates to use requested common timezone.\n *\n * This function is called during onload event (added to window.onload).\n *\n * @param {String} tzDefault: default timezone, if there is no cookie\n- * @param {String} tzCookieName: name of cookie to store timezone\n+ * @param {Object} tzCookieInfo: object literal with info about cookie to store timezone\n+ * @param {String} tzCookieInfo.name: name of cookie to store timezone\n * @param {String} tzClassName: denotes elements with date to be adjusted\n */\n-function onloadTZSetup(tzDefault, tzCookieName, tzClassName) {\n-\tvar tzCookie = getCookie(tzCookieName);\n-\tvar tz = tzCookie ?
