Craig Russell commented on OPENJPA-1480:
----------------------------------------

What is the database type for storing these timestamp values? Is there a column 
with the time zone? Where would you store the time zone information in the 
database?

> time zone info lost when using timestamp field

> Looks like OpenJPA always gets the time stamp out at the time zone of the 
> machine, not the time zone that was used originally.
> The test case is putting in 2 TimeStamps
>     TTimestamp = 4-3-2004 21:0:0.0 (America/New_York)
>     TTimestampUTC = 4-4-2004 2:0:0.0 (UTC)
> When OpenJPA gets those 2 timesamps back out of the database, they are 
>     TTimestamp = 4-3-2004 21:0:0.0 (America/New_York)
>     TTimestampUTC = 4-3-2004 21:0:0.0 (America/New_York)
