Perhaps, but part of the process of gpsd receiving data from a GPS
receiver involves the time of receipt matching the time of emission.
gpsfake breaks this assumption, and I am unaware of it having support to
fake that too.
Hence it is not surprising that time sync code is disabled for gpsfake.
I suggest hooking up a live receiver. Is there some reason you don't
want to to that, other than a desire for isolated component testing?
