When you commit (or import), Subversion stores the current date and
time in the revision. If you're importing a tree of files with
varying dates and times, and expect that to be preserved, you'll be
disappointed. :-)

There is a branch of Subversion which includes the saving of the date
and time. If this is necessary for you, you could use that branch
instead -- if it still works (I don't know).


Or, if you'd rather work with standard Subversion, you could commit
each JAR file in a separate revision, in chronological order would be
best, and then change each revision's svn:date property to the
modification date of the file. That would be tedious, but it would
work, and perhaps someone has already written a script to import a
directory that way. (I think I saw something like that months ago on
this list, but I could be imagining it.)

When you check files out of a repository, the default behavior is
that the files get the current timestamp. If you want to see instead
the timestamp of when the files were committed, then you uncomment
the line "use-commit-times = yes" in the file ~/.subversion/config.
