[Bug libgcj/15560] New: SimpleTimeZone doesn't handle on-or-before/after at ends of month

[jlquinn at gcc dot gnu dot org]

If you define a rule that goes beyond the ends of the month, getOffset will give
incorrect results.  For example,

timezone.setEndRule(Calendar.SEPTEMBER, -6, -Calendar.TUESDAY, 43200000);

refers to the tuesday on or before September 6.  In 2004, this is actually
August 31.

off = tz.getOffset(GregorianCalendar.AD, 2004, Calendar.AUGUST, 31,
Calendar.TUESDAY, 45000000);

should occur after the end rule, but will return before it.

See mauve test gnu.testlet.java.util.SimpleTimeZone.check12 for this example.
