Further comments: I am not as hardworking as u/woonie to use an analog watch and type every single timestamp, so I went with this Timestamper app to log all the timings. Despite this I still made a few mistakes so the timings given above might be off by a few seconds.
The app called timestamper should do exactly what you're looking for. Time and location. I think it has a widget too

Timestamper may work for you.
Time Stamper maybe what you're looking for.
TimeStamper is what you are looking for.
Are you the same developer from this identical much older app? Or are you copying it?
