What is the closest thing to 'date_default_timezone_set' in PHP4?

Question

How can I achieve a similar effect to 'date_default_timezone_set' in PHP4? I need to use the date() function while taking into account local time zones and also day light saving.

Edit: example with putenv:

putenv('TZ=Australia/Victoria');    
echo date('l jS \of F Y h:i:s A');

Outputs

Thursday 6th of October 2011 07:36:49 PM

Actual time here in Victoria

Answer 1

No solution came from this question. I ended up doing a manual work around using the Flash Player.

Answer 2

It looks like the TZ environment variable is what you would need to use for this. Using putenv() you should be able to dynamically change the timezone.
