Time-nuts, Is it a bad idea to have more than one PPS source on a single machine? Would this cause additional jitter when trying to compare the timestamps on two sources? I understand that USB can't deliver a real PPS, but what about using onboard serial ports or a PCI card?

I saw some hints that the USB DCD might depend on the chipset . I don't like gpsd so I try to avoid it but I might try it. Thanks. > Do not do it.
