Calendar issue when syncing

[Butokan]

I have a problem when I sync my TP2 with my computer. In my Outlook(2007) all my contacts and calendar events are correct. When I sync my phone, I get some calendar events that are a day off. I’ve tried making new contacts in Outlook, and it still syncs to my phone a day earlier. I’ve tried changing it in contacts and calendar, but it always shows someone’s birthday or calendar event listed a day ahead. For example if someone’s birthday was 9/23/75 in my Outlook, It would be 9/22/75 on my phone. Can someone help me fix this problem. I’m running Windows XP, Outlook 2007, and Activesync 4.5
