git log use of date format differs between Command Line and script usage.

If you supply a non-standard format to the date configuration for git
log, something like:
[log]
        date = format:%Y-%m-%d %H:%M

then, when you run 'git log' inside a script, or when using gitk (anywhere), it fails on decoding the format.

fatal: unknown date format format: %Y-%m-%d %H:%M

However, that format works correctly on the command line. I do not have a patch to address this issue.

I guess you have two versions of git on your system, and the one used in scripts is older than 2.6.0, which introduced this feature.

So I ran

    $ git config log.date  "format:%Y-%m-%d %H:%M"
    $ git config --list |grep log.date
    log.date=format:%Y-%m-%d %H:%M

Then I have a script as
  $ cat script.sh
  #!/bin/sh

  git log >out

after executing I get:

  $ head out

Also gitk seems to work here.

Rene's answer sounds reasonable, check the version(s) of Git on your system?

Yes. That is the case. Just confirmed it. I'll remove the old version. Sorry to have bothered the mailing list.

Thank you.
