One application is advanced network diagnostics eg cards like this:

So for a 40 GbE card, time-stamping 1 kilobyte packets demands
sub-microsecond accuracy, if you want to compare at different points
in your network.

I have spent a lot of time, effort, and money on developing my GPSDO without a whole of thought to the user base.  It was just a quest for the best result I could obtain with a particular technology.  The frequency standard users was a no brainer.  Everyone who wants a frequency standard eventually understands they need to get a GPSDO, or an Rb, or a Cs.  And that's all I thought I had: a good frequency standard.  And then Tom prodded me a bit and showed me the shortcomings of what I was doing, and I did something about it.  So, if an NTP user can get his time fix directly from a noisy receiver, who actually needs a time-accurate, low jitter 1PPS pulse?
