Let me see if I follow here.  If I am in the Eastern timezone and enter
a time for 9pm, 1/1/1850, and someone else in the Central timezone
enters the same time, if I look at the two dates from the Eastern
timezone I will see mine as 9pm and the other as 10pm?

Wow, I wonder if that is bad? 

It seems I would mix these in a table so it is the underlying data
representation that may be the problem.  Yikes.
