status.i4.v = dio_memory_time_set_c(num_devices.i4.v,
					    properties.i2a.r, time_set.u4a.r)

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

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

	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
