You don't need GPS or SMPTE if you have an Internet connection.  The
computer can use a set of NTP servers from the "pool" to get time.  The
result is good enough that the seed of sound delay resulting from your
random distance to the bell will be the largest source of error.

If you convert timing errors to distance at the speed of sound.   You would
need the GPS only if you car about bell to ear distances of about one foot,
give or take

So for this use case the OP does not need a GPS or even a SMTPE connection
just a WiFi link to the internet would be more than enough for controlling
a horn blast from a light house
