The time zone will be the time zone for your server. There is no way
for you to tell what the timezone on my machine is.

Your best bet is to just ask them what timezone they are in, and whether
or not to adjust for dst.

As for the dates of when to start/stop. I don't have any good
recommendations there. I suspect the timezones would set it
appropriately - but there are way too many to be usable, IMHO.
