58                 PHC    output PPS is from the PHC clock
62                 IRIG   output is from the PHC, in IRIG-B format
63                 DCF    output is from the PHC, in DCF format
76 		the PHC.  May be changed by writing one of the listed
246 Description:	(RW) When retrieving the PHC with the PTP SYS_OFFSET_EXTENDED
247 		ioctl, a system timestamp is made before and after the PHC
250 		with the PHC time.  This estimate may be wrong, as it depends
251 		on PCI latencies, and when the PHC time was latched
255 		retrieved PHC time.
258 		the estimated point where the FPGA latches the PHC time.  This
278 		which outputs the PHC time in NMEA ZDA format.
