Despite its description reading as if it reports a count, in context (range 1 to 4, used to index the timer configuration table) this object is actually the row index identifying which one of the chassis's four general-purpose global timers a given row of start/stop/interval/state configuration applies to. An admin needs this index to know which timer they're configuring when setting the paired uchasArTimerStartDate/StartTime/StopDate/StopTime/Interval objects, since those are all indexed by this same value. For example, a row with uchasArTimerIndex=3 groups together the start date, stop date, and interval settings that collectively define the schedule for Timer 3 specifically, as distinct from the other three timers' independent schedules.
