Description: Within the overall time period specified in the pmSchedTimePeriod object, the value of this object specifies the range of times in a day when the schedule is active.

This value is stored in a format based on the RFC 2445 format for 'time': The character 'T' followed by a 'time' string, followed by the solidus character, '/', followed by the character 'T', followed by a second time string. The first time indicates the beginning of the range, and the second time indicates the end. Thus, this value takes the following form:

'Thhmmss/Thhmmss'.

The second substring always identifies a later time than the first substring. To allow for ranges that span midnight, however, the value of the second string may be smaller than the value of the first substring. Thus, 'T080000/T210000' identifies the range from 0800 until 2100, whereas 'T210000/T080000' identifies the range from 2100 until 0800 of the following day.

When a range spans midnight, by definition it includes parts of two successive days. When one of these days is also selected by either the MonthOfYearMask, DayOfMonthMask, and/or DayOfWeekMask, but the other day is not, then the policy is active only during the portion of the range that falls on the selected day. For example, if the range extends from 2100

until 0800, and the day of week mask selects Monday and Tuesday, then the policy is active during the following three intervals:

From midnight Sunday until 0800 Monday From 2100 Monday until 0800 Tuesday From 2100 Tuesday until 23:59:59 Tuesday

Setting this value to 'T000000/T235959' will cause the schedule to act independently of the time of day.
