A DESCRIPTION OF THE PROBLEM :
If I set the environment variable TZ to the value
"EET-2EETDST,89/01:00:00,299/02:00:00" and run the following
piece of code:

Calendar rightNow = Calendar.getInstance();
System.out.println(rightNow.get(Calendar.DST_OFFSET));

I get the result 0.

Also, if I run the following piece of code:

Date time = new Date();
System.out.println(time.toString());

I get a result which is one hour before what I get if I type
"date" on the command line in the same shell.

If on the other hand, I set TZ to "EET" only, I get the
result 3600000 from the first piece of code and the result
of the second piece of code is the same as what I get from
typing "date" on the command line.

Conclusion: Java misses the DST information when specified
manually in TZ environment variable.

According to bug 4256581 this has been fixed, but the problem is still
reproducible using jdk 1.4 and jdk 1.3.1 on Solaris 7 and 8.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Set TZ environment variable to
EET-2EETDST,89/01:00:00,299/02:00:00

2. Create a program with the following code:
Calendar rightNow = Calendar.getInstance();
System.out.println(rightNow.get(Calendar.DST_OFFSET));
Date time = new Date();
System.out.println(time.toString());

3. Check the printouts and compare with the result of typing
"date" in the shell.

4. Try the same thing with the TZ environment variable set
to EET.


EXPECTED VERSUS ACTUAL BEHAVIOR :
I expected that when TZ was set to
EET-2EETDST,89/01:00:00,299/02:00:00 the printout of
Calendar rightNow = Calendar.getInstance();
System.out.println(rightNow.get(Calendar.DST_OFFSET));
would be the same (3600000) as when TZ was set to EET (when
being in the DST interval of course).

Instead I got 0 and 3600000 respectively.

Also I expected the printout of
Date time = new Date();
System.out.println(time.toString());
to give the same time as "date" on the command line.

Instead I got a result being one hour before that of "date".


This bug can be reproduced always.
