Use this class for reference:
import java.util.TimeZone;
public class TimeZoneTest
{
public static void main(String[] args)
{
System.out.println("user.timezone="
+ System.getProperty("user.timezone"));
System.out.println("TimeZone.getDefault="
+ TimeZone.getDefault());
}
}
On my system, this is the output with all defaults:
$ java TimeZoneTest
user.timezone=
TimeZone.getDefault=sun.util.calendar.ZoneInfo[id="America/New_York",offset=-18000000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/New_York,offset=-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]]

$ TZ=Asia/Calcutta java TimeZoneTest
user.timezone=
TimeZone.getDefault=sun.util.calendar.ZoneInfo[id="Asia/Calcutta",offset=19800000,dstSavings=0,useDaylight=false,transitions=6,lastRule=null]

What configuration effects this timezone setting? TZ environment
variable? Something else?

$ TZ=IST java TimeZoneTest
user.timezone=
TimeZone.getDefault=sun.util.calendar.ZoneInfo[id="IST",offset=19800000,dstSavings=0,useDaylight=false,transitions=6,lastRule=null]

Good.

What does your server report if you ask for
System.getProperty("user.timezone") and TimeZone.getDefault() while
Tomcat is running? What leads you to believe that either the JVM or
"Tomcat" is not running with the right TimeZone?

That seems like a drastic technique.
