Notes
Applications should not use this call with A(in) = 1, the system uses the call in this way to help maintain the time over soft reset. The call's function is to indicate how much time there is to elapse between the time given and the current time. This routine subtracts a small offset from the difference between wanted time and current time to allow for the routine processing overhead.
