Correction:  I was thinking of Faros, which syncs time with several
internet time servers, or with ToyNTP.  ToyNTP itself only works with a
hardware GPS on a real serial port.

The Red Pitaya time and frequency can also be calibrated using the same GPS
hardware, as explained in Pavel's documentation, under "GPS Interface"

I asked him if a GPS could also be used to calibrate sdr_receiver_hpsdr.
Unfortunately, no.  He said that would be a non-trivial enhancement.
