START_TIME for SYS.DEFTRAN is 2 hours behind CURRENT_TIMESTAMP

 We are using Advanced Replication (2-site multi-master, asynchronous, continuous push) on Oracle 10.2.0.4.0 running on Linux x86_64. While developing our monitoring queries, we uncovered an issue.

If we perform a transaction at 1:31:26 P.M. (Central time), the START_TIME column of the SYS.DEFTRAN view shows the transaction occurring at 11:31:26 A.M. It always seems like it is exactly 2 hours behind.

I looked in the system.def$_aqcall and system.def$_aqerror views that DEFTRAN queries, and the times were 2 hours behind there as well. Our O/S time zone is Central (CDT), DBTIMEZONE is "+00:00", and CURRENT_TIMESTAMP returns the local time with a "-05:00" offset. In addition, there have been no daylight savings time changes since we started the instance.

Howdy, Stranger!
