There's a few options, though there's not a PHP Class or Function that will automatically do it for you.


Use GeoIP and location-based matching to match the IP to a zone. The downside here, as with many solutions, is that if they are using a VPN or Proxy, it will show the zone of the VPN or Proxy IP, not the users physical IP that's behind it.

User Data

Have the user provide their timezone and you can do conversions against GMT.


Javascript is client-side, though much like GeoIP, if the client is behind a VPN or Proxy, the same issue persists. You won't be displaying the timezone of the user, you'll be displaying the timezone of the VPN or Proxy.
