/*++
Routine Description:
Sets the passed in systemtime to a time inside the discount rate period.
Some care must be taken here because the time passed in is in UTC time and the discount rate is
for the current time zone. Delineating a day must be done using the current time zone. We convert the
current time into the time zone specific time, run our time-setting algorithm, and then use an offset
of the change in the time-zone specific time to set the passed in UTC time.
Also, note that there are a few subtle subcases that depend on the order of the start and ending time
for the discount period.
Arguments:
CurrentTime - the current time of the job
Return Value:
none. modifies CurrentTime.
