Hi,

According to the git-log man page, we can configure how date are 
displayed:

--date={relative,local,default,iso,rfc}
   Only takes effect for dates shown in human-readable format,
   such as when using "--pretty".

But it doesn't work when a user supplied format is used:

git-log --date=short --pretty=format:"%ad"
Wed May 28 13:28:35 2008 +0200
Wed May 28 13:26:14 2008 +0200
...

instead of
2008-05-28
2008-05-28
...

In pretty.c, when pretty_print_commit() calls format_commit_message(),
dmode isn't passed as argument so format_commit_item() will never have
the date format specified at the command line.
This problem is present in git-1.5.5.3

Regards,

 	Christophe

Sorry, in theory, perhaps they could, but it doesn't and it never did.
The output is working as designed and intended.

You probably could send a patch to add %aT and %cT that are defined as
"author/committer date in the format specified with --date=<this> option";
but "%ad" and "%cd" are defined to emit "author/committer date always in
the default format".
