/**

|
* zones (the UNIX zones), and those change from time to time, this
|
|
* test can fail after a zone table update. If that happens, the
|
|
* selected zones need to be updated to have the behavior
|
|
* expected. That is, they should have DST, not have DST, and have DST
|
|
* -- other than that this test isn't picky. 12/3/99 aliu

* Test the behavior of SimpleTimeZone at the transition into and out of DST.
