Online missions

Hey! Can anyone help me out with what time zone does the game go by when new online missions start? Having a hard time figuring it out since I live on Guam. Always starting late -.-’

From the past ones, the time zone was eastern.

5Pm EST (The time the events normally start is roughly 8am local time for you the following calendar day. So if the next event starts 12/14/2013 5:00pm EST, it will start 12/15/2013 8:00am in guam, You are US EST +15(GMT+10). The events normally also post the start time in GMT, so just take that value, and add 10 hours to get the event start time in your local time. I hope that helps
