status.i4.v = mio_time_set(num_devices.i4.v, device_indices.i4a.r,
				   properties.i2a.r, time_set.i4a.r)

	This routine returns the time a device/property was set in the
	MIO datapool.  If it has never been set, the returned time will
	be 0.

	num_devices	number of devices
	device_indices	device indexes
	properties	property indexes
	time_set	returns time of day set for each item in the list
			units are: seconds since 00:00:00 January 1, 1970

	This function returns ACNET status values as follows:

	OK			success
	negative value		overall ACNET error

	This function requires the following include files:

	dbprops_h, diolib_h, acnet_errors_h

	Related functions:

	dio_simulate, mio_set, mio_control, mio_cancel, mio_fill_status

	C/C++ usage:

	static const short	properties[NUM_DEVICES] = {PRSET, PRSET};
	int	status;
	int	num_devices = NUM_DEVICES;
	static const int	device_indices[NUM_DEVICES] = {14430, 14431};
	int	time_set[NUM_DEVICES];

	status = mio_time_set(num_devices,device_indices,properties,
