== History of an individual file ==
Text mode
{{{
git log -p <filename>
}}}

Graphically
{{{
gitk <filename>
}}}

== Find revision by date ==
This is kind of obtuse, and I really recommend {{{ git log }}} or {{{ gitk }}}. If you insist:
{{{
git rev-list -n 1 --before="2009-07-27 13:37" master
}}}
This finds one revision (-n 1) before a certain date. You can use this with {{{ git checkout }}} (see below).

== Check out old version of a file ==
Find the old revision by using {{{ git log }}} (see above).
{{{
git checkout <revision> <file>
}}}

Reverting to the current version (HEAD):
{{{
git checkout HEAD <file>
}}}

== Set file modifcation times to last commit ==

Here's a [attachment:git-touch.py little script] to walk through {{{git log }}} output, find the commit times for each file and call {{{touch}}} on them.  Call it from the root of the checked out repository.  {{{git}}} and {{{touch}}} need to be in your path.  I was able to set times on the {{{abac}}} git repository by:
{{{
$ cd abac
$ python ../git-touch.py
}}}

No warranty.  As is.
