* java/util/Calendar.java: Fix typo in comment.
(set): Set 24-hour clock hour instead of 12-hour clock hour.

needed for evaluating numbers '0' to '9' in printouts of GMT offsets.
* java/util/natGregorianCalendar.cc (computeTime): Properly handle
timezones and GMT offsets, being careful to account for units of
milliseconds vs. seconds.
