To get a time resolution of 10 ms (yes 10X 1 ms), you don’t really need the 
pps. The timing of
the serial string is probably “good enough”. That assumes you don’t have all 
sorts of other
messages  turned on as well. In the case of a wall clock, it’s not clear why 
anything other
than a basic timing message would be enabled.  A sub $10 module likely will 
do everything
you need to do.


I'd second Gary E. Miller's comments.  Serial typically isn't good enough 
for 10 ms, and may have a significant offset.
