Re: Is there really no way to keep the file modification time intact?

Excellent response, Graeme. To take it one step farther,
the lost information about modified time hurts
whenever the modified time is before the created time.

In both windows and *nix systems, the most common ways of
copying (mv, cp, move, copy, mouse-move, mouse-copy,
winzip, xcopy, etc.) ALL preserve the modified date
of the files.

The real question should not be "which tools use the modified
date", but "which tools do not use the modified date".

Therefore, consider the Use Case of versioning log files
(as opposed to source files). One would like to know
the modification date of the file because the file's
identity involves its last mod time. It would serve as
a welcome short cut to finding the correct file (like
a hash code) if svn would co the files with their
original mod dates.
