It is in seconds since the unix-epoch.  An "amount of seconds since" has
no concept of timezones.

As you can see, specifying "-u" (use utc) does not matter for the epoch
time whereas it does for wallclock time.

I ask you to respect any "Reply-To" and "Mail-Follow-Up" headers.  If
you reply to me off-list, you'd better tell me you're doing so.  If
you don't, and if I reply to the list, that's your problem, not mine.
