Als ik date_default_timezone_set('CET'); aan het begin van het script zet krijg een foutmelding.
Fatal error: Call to undefined function: date_default_timezone_set() in /mnt/web2/10/31/51359131/htdocs/develop/poll/polljw2011.php on line 16
Of ligt dat soms aan de php versie 4.4.9 op de server. Ik begin het probleem te begrijpen. Op mijn laptop 5.3.2. In neem aan dat het dus aan de php versie ligt, maar hoe los ik dit nu op?

Maar zie mijn aanvulling.
Spelen met de volgende value date_default_timezone_set('UTC'); doet in mij geval niks.
