Possible bug in git log with date ranges

Possible bug in git log with date ranges

[David Hoyle]

Hi,

Hopefully I've read the readme file correctly for submitting something
that might be a bug.

I've recently migrated projects from an old version control system
(JEDI VCS) to Git (which I really like BTW). The way this was done was
by extracting the files from the original database and saving them to
a folder layout and then running git add / commit on the files. When
using the commit command I've used the --date switch to commit the
files using their original dates. However if I run git log with say
--since=date it seems as if this command uses the actual date the
commit was entered not the date given for the commit. The same seems
to apply to the other date filtering switches.

Below is an example using a log alias switch shows dates in a single
line format.

The --date=* switch to git-commit sets the author date, but the date
narrowing options to git-log use the committer date. See if when you
run:

    git log --pretty=format:"%aD - %cD"

Whether what you're getting doesn't make sense in terms of the second
date.

You can use GIT_COMMITTER_DATE to get what you want, see "DATE FORMATS"
in git-commit(1).
