* CANNOT REPRODUDE
*
* Yet another _alleged_ bug in TimeZone::getOffset(), a method that never
* should have been made public. It's simply too hard to use correctly.
*
* The original test code failed to do the following:
* (1) Call Calendar::setTime() before getting the fields!
* (2) Use the right millis (as usual) for getOffset(); they were passing
* in the MILLIS field, instead of the STANDARD MILLIS IN DAY.
* When you fix these two problems, the test passes, as expected.
