This might be old news, but not seeing any discussion here, it may be worth posting.
If you have a REALLY old GPS (say year 2000 or earlier), there can be major problems with time keeping as of April 6, 2019.
For the somewhat snarky general explanation, see:

For the official, somewhat technical, US Naval Observatory explanation, see:

Cheers and great hiking!

Should add that the potential time error can lead to significant position errors.

Re: Possible OLD GPS Errors, April, 2019
thanks for the info
so, on April 6, 2019, if you have an old GPS, it may start getting large position errors
I will check mine after April 6 just to make sure

All of mine survived. I have one made in about 2000. It just has a daylight savings error since we changed that somewhat recently. I can manually adjust DST though.
