windows - Does putting a computer to sleep pause shutdown timer?

I have a script I use to shutdown all of the computers at my work location after 4 hours that I run everyday. Lately, I've been getting reports of users computers shutting down in the middle of the day instead of at night when they are supposed to. I'm thinking these users must be receiving the shutdown command while on location and then taking their machine home in either sleep mode or hibernate (after letting the battery die... :/) and when they turn it back on, the shutdown timer continues from where it left off.

So, my question is, does putting a computer to sleep or hibernate pause the shutdown timer and, if so, can I stop that from happening?

EDIT: The timer in question is the shutdown /t command.
