You could maybe try this wordpress plugin - http://wordpress.org/extend/plugins/placewidget-f...

Hi lanili, I had some issues with Facebook and different timezones too since I'm in the UK. The only way I could get it to kinda work is to play around with the event time by taking away the relevant amount of hours (e.g. the time difference from your timezone and the US) and then check if facebook created the right date and time. Let me know if you find a better way :)

thx tristan, good to see that you worked out! now other people can benefit, including me :)

first comment using the new #intensedebate plugin :)
