hi,
we have tomcat 7.0.68 deployed on linux.
To capture the log in local system timezone using ExtendedAccessLogValve
class we change the following line
"currentTimestampFormat.setTimeZone(TimeZone.getTimeZone("GMT"))"
into
"currentTimestampFormat.setTimeZone(TimeZone.getDefault())"
in ElementTimestampStruct class and then compile and replace the
catalina.jar in already deployed tomcat.
Now , The time is sync with the system set time which is GMT+5 but somehow
date is still operating on GMT as date get changed at 05:00 AM ( system
time). please help me in this regard to understand why the above mentioned
change have no impact of date field.
Regards
Farhan
