Use the timeout parameter of EvtGetEvent.

Correct. And when the device is off, it's only accurate to about a minute.

Why post events to the queue? Just compute the timeout parameter. Every time
EvtGetEvent returns, check the current tickcount to see if it's really time for your
code to run (because there may have been some other reason you received a null event).
