timestamps problem

[lacdan]

Hi, Orux
I use 7.4.22 version. I have been using oruxmaps for several years and the timestamp dates have always been different (20 years) from the day dates. For example :
Recording date: 2019-10-28     Gpx date : 2019-10-28    Timestamp date : 1999-10-29

It happened also but rarely that the date recorded in the gpx file differs from the recording date !
    Recording date: 2019-11-04     Gpx date : 2000-03-20    Timestamp date : 1980-03-21

Since last february track recording has stopped twice due to a big change in dates between the last two points as you can see below.
First crash, on 2020-02-03 :
  Last but one point :
        Gpx date : 2000-06-19   Timestamp date : 1980-06-20
  Last point : 20 years later !
        Gpx date : 2020-02-03   Timestamp date : 2000-02-04
Second crash, on 2020-04-22:
  Last but one point :
        Gpx date : 2020-04-22   Timestamp date : 2000-04-23
  Last point : 20 years earlier !
        Gpx date : 2000-09-06   Timestamp date : 0980-09-07

Do you know how to solve this problem ? Thank you for your assistance.

Hello!
It is the well know 'gps week rollover problem': https://en.wikipedia.org/wiki/GPS_Week_Number_Rollover

If you don't have a firmware patch for your device, check the last beta version, includes an option to change GPS timestamps.

Hi Orux, I have downloaded last beta version and used it several times without any problem. But today, between two points, the date changed from 2020-05-08 till 2039-12-23 and of course recording crashed. May I send you the files ? Thanks. Lacdan
