OT week runs Sunday 00:00 to Saturday 23:59.
Pay Period starts (on go live) 9/1/17.
9/1/17 is a Friday.
So the punches from the Sunday before 9/1/17 (8/27/17)
should count torwards OT for the week ending that Saturday night 9/2/17 at
23:59.
But since the data before go live is just a report in
Historical data it does not calculate the time before 9/1/17 for OT. So
if they went into OT it does not have the previous time in TC8 to use for that
to happen.
