WN - IE problem

Hej! Jag har ett enkelt javascript som ska visa tiden kvar till ett speciellt evenemang. Koden ser ni nedan och ni ser resultatet på www.gbfestival.se . Det som IE hackar på är att han inte vill få ut ett värde med Date.parse() . Det står "Object doesn't support this property or method"
Vad är fel? Det fungerar i alla andra webbläsare jag testat

Koden:

Kod:
