Re: Determine Time in other Time Zone - Mailing list pgsql-general

I don't think I've got anything useful to add except maybe to offer some
thoughts.

First, do your users use postgres from their machine via ssh? The Web? Some
other way? If it's from the web, perhaps you could include some code about
localtime and have that sent to your server when people log in. If it's via
ssh I don't know. Maybe you could write a short script that would poll the
remote machine's timezone data...(<major shrug> I'm an amateur! :-)

Second, perhaps this sort of problem has been solved via the ntp software?
ntp polls various time servers. Perhaps there is a way to call a timeserver
that is local to where ever the users are logging in from.

Third, so far I haven't mentioned postgresql in any of this. But it sounds
like it's just a matter of taking externel information and making it
internal...

Oh well, these are just my thoughts!
