Time loses if the connection has not set before start tracking

[sokolovvs]

Steps to reproduce:

1. disable your connection
2. run your application
3. start tracking, wait
4. enable the connection
5. stop tracking
6. close the application

I could reproduce this problem and for a long time interval

I used Ubuntu 18.04.5 LTS, Cattr-2.4.5.AppImage
