Good day,
I plan getting a B210. I can call set_time_now with the UHD interface
but there must be latency involved, between the time I do the call and
the time it is updated. Can I set or reset the time through the GPIO?
My idea is to have a switching network piloted by Arduino or similar.
The code receiving the samples from B210 needs to know where those
samples came from. That's why I thought of changing the timestamp, so
that the code receiving could notice something happened (eg the time
was reset or modified).
Thanks.

You can use set_time_next_pps(), and use the PPS input as a trigger input.
