    I had a chance to toss it out in the backyard for an hour yesterday, and yes, that did it. So this nearly 20-year-old GPS receiver is now reporting all data correctly: lat, lon, and UTC. I believe it's only using the GPS satellites (I doubt it was Glonass-capable since that system was in decline back then). My phone gives a better fix, but it's only a moderate difference. I have no viable use for the old thing, but it's nice to know that the tech is relatively robust.
