What we use, and works for us with both the linux 1.3.0 jdk on intel (on
FreeBSD) and the solaris 1.3.0 jdk on sparc is "export TZ=CST6CDT".

solaris8$ java -version
java version "1.3.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_01)
Java HotSpot(TM) Client VM (build 1.3.0_01, mixed mode)
solaris8$ export TZ=CST6CDT
solaris8$ java TestRun
The TZ is: CST
solaris8$ unset TZ
solaris8$ java TestRun
The TZ is: GMT-06:00

FreeBSD$ java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Classic VM (build 1.3.0, green threads, nojit)
FreeBSD$ export TZ=CST6CDT
FreeBSD$ java TestRun
The TZ is: CST
FreeBSD$ unset TZ
FreeBSD$ java TestRun
The TZ is: GMT-06:00

Seem's pretty consistent.  Sorry I don't have any other versions of the
jdk handy to test with.
