This read-write field sets the calendar date on which the associated global timer's schedule becomes active, compared against the management entity's own system date, time, and configured timezone, defaulting to the vendor placeholder of 01/01/95 until an admin sets a real value. An admin must configure both this and uchasArTimerStopDate before a timer will actually do anything useful, since a timer left at its default 1995 start date combined with a future stop date would already be active. For example, an admin scheduling a monthly maintenance script would set this to a specific date like 09/01/26 to mark when that timer's recurring firings, governed separately by uchasArTimerInterval, should begin.
