setting the default time zone

Well I asked a simple question to deal with time zones ( range(-12,12) ), so he told me to look up date_default_timezone_set(), but I'm unclear on how to use it. How would I use that for creating a basic time zone script for dates?

To note my question was, how could I create a timezone script, if the default time() on different servers are always different?

date_default_timezone_set() allows you to change the timezone for your script. For example:

PHP Code:


			
date_default_timezone_set('Europe/London');

echo date('H:i:s', time());

// shows: 17:13:40



date_default_timezone_set('Australia/Tasmania');

echo date('H:i:s', time());

// shows: 04:13:40

As you can see, date() has given us different times depending on what timezone we have set.

You can provide this functionality by storing the users timezone choice (full list: PHP: List of Supported Timezones - Manual) then using date_default_timezone_set() before you run any date/time functions.

Also, PHP5 expects you to set a default timezone using date_default_timezone_set() before you use any date functions

Okay how do I find out different times zones for GMT ? Right now im in -6GMT Central Standard Time. How could I use that function, but based on the different GMT (ie:: range(-12,12) ).

I'm not entirely sure what you are trying to achieve. Can you provide a bit more detail on what you want to do?

Go in your vb control panel and change your GMT time to fit your timezone.
