public class SimpleTimeZone
SimpleTimeZone
is a concrete subclass of TimeZone
that represents a time zone for use with a Gregorian calendar. This
class does not handle historical changes.
Use a negative value for dayOfWeekInMonth
to indicate that
SimpleTimeZone
should count from the end of the month backwards.
For example, Daylight Savings Time ends at the last
(dayOfWeekInMonth = -1) Sunday in October, at 2 AM in standard time.
