Hi Normally a date roll over bug is a non-fixable item in these older devices. The basic GPS modules simply did not start to have the “smarts” to handle this until at least a decade after they went out of production.
Simple answer is to leave it as is and just use the frequency output. If you need time, get a $10 USB GPS “stick” …. way cheaper than hacking a working device.
