The value of the object tPeriodicTimeRangeEndWeekDay specifies
the end day-of-the-week of this periodic time-range entry.
In case the startday (tPeriodicTimeRangeStartWeekDay)contains a
wildcard (i.e daily(7), weekday(8), or weekend(9)), the value of the
object tPeriodicTimeRangeEndWeekDay must be equal to
tPeriodicTimeRangeStartWeekDay. If no value is specified at row
creation, this object defaults to the same value as
tPeriodicTimeRangeStartWeekDay.
