Log4j Date logging issue
Hi,
We use log4j.jar to log our application's debug statements.
Debug() and error() methods of Category class is used for logging.
In the recent past, the System time was upgraded for US 2007 DST
changes.
After this change, Log4j %d shows the date like, 2007-03-18
23:01:14,909, when the actual systemtime is 03/19/2007 00:01:14.
We are not sure where log4j gets the previous day timestamp from.
Pls help us on this.
Log extract :

Be advised - java date and time calculations will still be inaccurate
even if the host OS has been updated with DST 2007 updates on older VM
builds. Per the Sun documentation regarding DST updates you still
must either patch your affected JRE with the free tz_update program or
upgrade to a newer JRE altogether.

I would attemp to make a small program that prints the current data
and time in the same format to confirm that it is the JRE or OS. You
may need JRE patch that supports the changed DST dates.
