[PHP] Timezones and Daylight Savings Time

[Jeff McKeon]

What if you set the server to use UTC and then used the clients local
system setting to offset it for each client?

So the server would have it's time at UTC and a client in the Eastern US
would be at -4. You could then detect the web client timezone setting
and adjust as needed?

This is just a logic suggestion, I have no idea if it's possible with
code but I would imagin it would be..

They want everything set to their time, so it would
probably be easier just to determine the server time
and add as necessary. I think...
