specified, and that date/time is before the current date/time, $SL WAKE will be immediately 

issued.

In sleep mode, the real-time clock is not GPS disciplined, and is therefore subject to some

degree of drift. The longer the Tracker is asleep, the more the drift will accumulate. The user

should be aware of this when selecting a sleep with a long duration.

Example:

Commanding the Tracker to sleep for 1 minute:

$SL S=60*57

$SL OK*3b

$SL WAKE,TIME @ 2019-04-11 18:58:03*77
