92. Timezone jumping    forums.oracle.com

Like DrClap says, I don't know how exactly the DB stores it, but that's irrelevant.

94. Possible problem with TimeZone.getOffset() ?    forums.oracle.com

When converting from GMT to a local time zone, I noticed that the getOffset() function does not seem to take into account daylight saving time.

97. How to show 3-letter Timezone in java code?    forums.oracle.com

Given the raw offset from GMT in milliseconds, I want to show a date with timezone (3-letter) in Java code, a date looks like 'Feb 12, 2007 EST'.

Does anyone know how I can get the 3-letter ...
