You need the time indication to figure out which second boundary the PPS
signal is referring to. But once you are accurate to much less than half a
second, the PPS is far more accurate than a time indication sent over RS232.
This is especially true with GPS receivers that don't specify the
relationship between the RS232 time output and the UTC second boundary, and
most don't.
