Hello, I am on 3.0.8, and my Win XP Sp3 guest stopped being in sync with the host (Ubuntu 9.04)
I can't say it time sync broke right after the upgrade, but it did work before.

Did you also install the guest additions?

yes, in fact i even upgraded it, as older one had issues with webex

well, this issue just went away on it's own
