TsctlTimeTimeoutQDesc

This function returns true if the specified end time relative to the specified start time has been reached.

Note that since the tick value can roll over, the actual amount of time available to detect a timeout is equal to the total time for the tick to iterate through all values, minus the number of ticks between start and end. (end can be less than start; this function will correctly handle roll-over). Therefore, it is recommended that the user not try to measure times too close to the maximum possible (for example, within a few seconds, or the maximum amount of time between calls to TimeoutQ.)

If start and end are equal, then this function will always return true.
