Freid counts to 100, then puts out one finger. He does this for all 10 of his fingers, then digs a shallow groove in the ground and thinks to himself, "Ten minutes."
He continues with his counting and marking grooves in the ground until he has 12 grooves saying to himself, "That should be about 2 hours."
Rising he stretches and moves over to Karl and shakes his shoulder, being careful to avoid Karl's possible attack from being startled, then whispers to him, "Karl, it's your watch. Wake Leudigar in a couple of hours."
All assuming that there are no encounters that pop up...
I'm figuring that Freid counts a little faster than 1 per second, maybe about 100 per minute. If it's now around 1 am, then there should be about 2 hours per shift.
