Can you tell us more about the library that reads the i2c and sends
the data to udp?

Can you connect to the port, say with netcat, and see data?  If so,
grab a 30 second sample and send it here.

Which it always does.

Much better to send us the log so ww can see ourselve.s  It sounds like
you are getting some NMEA, but no ZDA.  gpsd, and any other decoder,
needs ZDA.

Beats me.  Show us what you see.  That would be a capture of the
raw data in udp, and the -D2 log.
