SYNTAX            : -2 ;T

RESULTING RANGE   : Seconds, Microseconds

FUNCTION          : Return the number of microseconds TV has been active.

ARGUMENT          : -2 (fixed).

NOTE 1            : The two resulting values separately give the seconds
                    and microseconds part of the time TV has been active.
                    The latter value will never exceed 999999.

NOTE 2            :  The operating system does not necessarily give back
                    microsecond resolution, though. So it is possible that
                    final digits are consistently 0, or seemingly random
                    values suggest a precision that is not actually there.
