I'm sure this can be done (?) (in clearcase it would be quite simple).

Note: In distributed systems (like Git) the recorded dates and times may not be 100% reliable or accurate since they may be recorded on a myriad of machines. Hopefully most machines are reasonably close to the “real time”, but there may be oddball outliers lurking in the network of contributors.

Don't forget file timestamp are not recorded in a DVCS like Git.
Only commit timestamp are there, and you can checkout easily a commit from a certain date.
git checkout master@{1 month 2 weeks 3 days 1 hour 1 second ago}
(Note: such a checkout would give you a detached HEAD)
In ClearCase, this is easy provided you set the "preserve file time" option to true.
(if not, you actually record the checkin time of each file, which is a bit like the Git commit timestamp, except for every files)

Use git log to determine a suitable revision to switch to, e.g.:
git log --since='2010-04-01' --until='2010-04-02'
This will show all the commits on 2010-04-01, so just pick the one that corresponds to the instant you want the files for, and note its commit id. Then just use git checkout COMMIT-ID to switch the workspace to that commit. This will detach your workspace (HEAD) from the current branch, use git checkout master to return.
