So I'm guessing that even before the zip file is re-created, the rebuild
process is leaking the rebuild timestamp into the last-modified metadata
of the generated marble-ipc-d-356.txt file?  That seems like it should
be handled by the build process explicitly setting its timestamp to
something related to the last-source-code-checkin time (with "touch
--date=XXX") rather than to current time.

Truncating the timestamps to DOS timestamps wouldn't work to eliminate
this difference anyway, since the date in the two files is two days
different; DOS timestamps are accurate to 2 seconds, as I recall.
