Time Zone Issue on Oracle WebLogic Server (Doc ID 1321214.1)

Last updated on FEBRUARY 01, 2024

Applies to:

Oracle WebLogic Server - Version 9.2 to 10.3.5
Information in this document applies to any platform.

Goal

In WebLogic Server 8.1, customers could use an EST timezone ID. For example, that time zone ID could be set in the postStart method of implementation class of "ApplicationLifecycleListener" using code TimeZone.setDefault(TimeZone.getTimeZone("EST"));. In 8.1, this time zone ID was handling daylight saving correctly.

In WLS 10.3 and above, this time zone setting was only handling EST time, meaning that daylight saving is ignored. For example, 7 pm EDT returns 6 pm (the time without the daylight saving adjustment). During EST, if the system time is 7 pm it was returning 7 pm.
