Period Element

Specifies how often the task needs to be started during Automatic maintenance.

The format for this string is PnYnMnDTnHnMnS, where nY is the number of years, nM is the number of months, nD is the number of days, T is the date/time separator, nH is the number of hours, nM is the number of minutes, and nS is the number of seconds (for example, "PT5M" specifies 5 minutes and "P1M4DT2H5M" specifies one month, four days, two hours, and five minutes). The minimum value is one minute. For more information about the duration type, see XML Schema Part 2: Datatypes Second Edition.
