Agreed about the clock. It's hard to imagine any logging software that 
can't do a time sync with a NIST server, unless you're in the boonies. 
My wristwatch claims to sync with WWV nightly.
I'm not sure what leeway LoTW (or some contests) allows for matching but 
it might be as tight as 30 seconds.
