BatchVariable BatchVariable is used when the period length can
vary and a special batch variable in a history table
determines the period start times.
NOTE: Offset and Periods are supported with
period variables, but not OffsetUnit and
PeriodsUnit.
BatchHistory Defines the history table which contains the values
for the batch variable. This must be defined when
BatchVariable is defined.
SchedulerId The scheduler identifier of the

scheduling of this task.
ScheduleBaseTime The base time of the calculation schedule.
ScheduleInterval The interval of the calculation schedule.
ScheduleIntervalUnit The time unit of the interval.

time, instead of UTC time.
