Which clock in particular? How much off?
If it's a DX obejct, I think it should be pretty much in sync with your puter.  But there is known problem with one clock plugin, where the hour hand only changes on the hour (at 0 minutes). Alberto released an update of the plugin but maybe not all object authors updated their clock object. I haven't updated my Christmas Time object because... well because Christmas is over I guess, so I should fix it before next Christmas.

It is the "Comic Imagine Clock," Travis. It tells me that the item was developed for a newer version of DX, but I have the most current version. In fact, I only bought the suite 2 days ago, and the Stardock Central interface confirms I have the most recent version (2.00a.012).

Ahhhhhhhhhh.... bueno!
