time problem?

[dadamssg]

i have an if stmt that checks if an end datetime the user selected is ealier than now. if it is it will say that the event has already ended and they need to fix their date & time. for most computers it works great. but the comp im on now at work will say the event has already ended. however on the page i echo the current datetime and its grabbing the correct time...does anyone know what could possibly be happenning?

[Maq]

Can we see some code?

heres the whole thing...its super messy..filled with a bunch of variables that i was testing that don't get used so i need to go back and clean it up but if you can help that would be MUCH appreciated.
