In my deployment config below i have the patch job set to deploy at midnight on Sat and end at  5:59AM. 

My DTC server is EST.   My Client Machine is PST. This is a three hour difference between them.

So assuming the box checks in at 12:01 EST (9:01 PST). That means it wont actually start deploying its package until 3:01 EST (12:01 Local PST), since its West coast. This means that It would continue to deploy until 8:59 AM EST (5:59AM EST).

Am i understanding the timing and time zones difference and config files correctly? That the deployment config is specific to the local host not the actual DTC server?
