Most people use ntp, and are in general concerned with keeping their 
clocks in sync as lots of other software depend on it (calender 
functions, fe). It shouldn't be the task of project leaders to make sure 
that the ~50000 random people around the world that submit patches to 
opensource projects every day all have their clocks in sync.

Can be done using reflog. Feel free to submit patches. Make sure you 
sync your clock to whatever ntp-server or other timekeeping mechanism 
Junio uses before you commit and send your patch though. ;-)

See the reflog response and, again, feel free to submit patches.

To get you started, I think the easiest way would be to teach gitweb 
about the reflog, and then insert a line saying
"--- pushed to this repo $date ---"
or something like that in the summary page whenever a commit is found 
that is also in the reflog. This should also be fairly CPU efficient if 
my guesses on how gitweb and the reflog works are correct. CBA to check, 
since I sincerely and whole-heartedly don't care about it myself.
