Time difference between SYSDATE on different sessions

Kevin HondeApr 29 2014 — edited Apr 29 2014

I have a database that is showing different SYSDATE time between two sessions;

     1. one connect using the ENV parameters - this shows the correct time as per OS date/time

     2. the other using @SID_NAME - this shows time 4 hrs behind

My system is a single node DB using ASM.

How can I correct this anomaly, I have tried restarting the LISTENER but with no joy.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC0)))
