You can get their timezone offset with JavaScript.

The most popular (==standard?) way of determining the time zone I've seen around is simply asking the user ximself. If your website requires subscription, this could be saved in the users' profile data. For anon users, the dates could be displayed as UTC or GMT or some such.

I'm not trying to be a smart-alec. It's just that sometimes some problems have finer solutions outside of any programming context.

Determine a User's Timezone

1. Get the IP of the visitor by using this:
   $visitorIP = $_SERVER['REMOTE_ADDR'];

2. Map it to country / city. There are many IP to country database available. I prefer MaxMind GeoIP Country Database and MaxMind GeoIP City Database.

3. Convert the timezone to that country / city.
