Returns whether the date/time is the second occurrence of this time. This is only applicable to a date/time expressed in terms of a time zone (type TimeZone or LocalZone), around the time of change from daylight savings to standard time. When a shift from daylight savings time to standard time occurs, the local times (typically the previous hour) immediately preceding the shift occur twice. For example, if a time shift of 1 hour happens at 03:00, the clock jumps backwards to 02:00, so the local times between 02:00:00 and 02:59:59 occur once before the shift, and again after the shift. For instances which are not of type TimeZone, or when the date/time is not near to a time shift, false is returned.
