NAME
        TR_GETSYSTIME -- get the system time.

   FUNCTION
        Ask the system what time it is.  The system time starts off at
        zero at power on, but may be initialized via the tr_setsystime
        call.

        System time is monotonically increasing, and guaranteed to be
        unique (except when the system time is set backwards).

   TIMER REQUEST
        io_Message      mn_ReplyPort initialized
        io_Device       preset by timer in opendevice
        io_Unit         preset by timer in opendevice
        io_Command      TR_GETSYSTIME
        io_Flags        IOF_QUICK permitted

   RESULTS
        tr_time         a timeval structure with the current system
                            time

   NOTES
        This function may be called from interrupts.
