[time-nuts] verifying synchronization with PPS

[David J Taylor]

From: Steve Summit

My specific question concerns the case that one of the boxes is
a computer, for example, a Linux box with time kept using ntpd
or chrony (perhaps also listening to a PPS signal coming in on a
serial port).  But I've never seen a computer with a PPS *output*.
=============================


Steve,

Folkert van Heusden has a driver for NTP which includes PPS output:

Perhaps this might help?

Cheers,
David
