I'm running a Ubuntu VM with VirtualBox and I have both the
virtualbox-guest-additions packages installed. I read in this answer that the system clock should sync with the host automatically with the Guest Additions, but mine doesn't seem to be doing that. What are some possible reasons / how do I rectify this? I've tried searching for this all over but most of the hits I get off Google tell you how to disable the automatic time sync, not enable it.
My host machine is running OS X 10.8, if that's of any help.
