You are the second person I hear say that. Why is preserving timestamps 
important? What use is there for it?

Git already tracks the commit date/time, authored date/time and other 
metadata - all available in the Git log. Those are git log metadata. But 
Git really only tracks file content changes over time - that is the 
important bit everybody needs. Git doesn't even track directories - only 
file content changes are tracked, but even with only that information, 
Git is clever enough to track file renames and movement of files between 
locations in the repository.

I honestly see no need for timestamps. If mean for things like a 
compiler should detect when files are changes - well, compilers should 
check for the content of file changes (via checksums or CRC etc). 
Timestamps can be spoofed or changed without the contents of the file 
changing - thus totally pointless. Then there is things like daylight 
savings time, timestamps across timezones etc. All things that could 
affect timestamps, but not the content of a file. So Git is right by not 
bothering with file timestamps - query the git-log instead.
