Have you considered configuring NTP? That should automagically keep
your clock set to the right time. You will require servers that know
what the correct time is but there are hundreds of publicly accessible
NTP servers. It will not do much for you if you shut down your desktop
system when you are not using it! If you leave it on, you can stay
within milliseconds or even microseconds of the correct time.
