Is this a desktop you're working on, and not something mission critical? If so, what is significant about the timing error? If you're a typical humanoid, then bank on 0.3secs reaction time. A fair whack of that 0.3secs is the mind "realising"; it is only relevant if you are to compete against a machine. And I think you are going to need a "machine" to do the timing - when the CPU shuts down, it sorta stops timing/signalling stuff, software stops working....
Open the door. Go outside. Occasionally.
