Git enhancement request - checkout (clone) set modified dates to commit date

Hello,

there are several timestamps in the lifecycle of a modification to a file in Git:

	• file write timestamp
	• git add timestamp
	• git commit timestamp
	• git push timestamp
	• git merge timestamp
	• git checkout timestamp

Right now when I check out/clone a repository, all the files have the checkout timestamp as

	• ctime - creation time for the file
	• mtime - modification time for the file
	• atime - las access time for the file

Not only does this force more work for timestamp-based build programs, it also deprives me, as a developer, of a visual 'file blame' that could be very useful in spotting changes without having to do git log over and over.

I would like to propose that the checkout process set the create and modification times of a file to the timestamp at which a file was committed.

When repository servers have different clocks - which is normal - each clone/merge/push should record the time offset.  Each timestamp on each commit should be corrected to the repository's specific time, and that should be a marking on the history.

Sincere regards,

Andrew Wolfe
