Re: [Q] What might cause modification dates to shift later by an hour?



One easy workaround would be to, when you start the backup program, to set it to a timezone that does not have  daylight savings time shifts.  (eg: " TZ=MST  run_my_backup"  )

This can be done on a per-process (or per-user) basis by setting the TZ environment  variable before
starting the process (or in a user's .*profile file)

If you check the absolute time stamp (which is GMT), it hasn't changed...
but the distance between you and GMT changed by one hour when the DST change kicked in.
Nothing has gone wrong, unless your backup software works internally with TZ shifted date stamps, in which
case it might get confused twice per yer.

Thanks for you answer. It looks like a bug in the backup software.
