Hello
I have been starting to convert some .mts-files to .mp4. The .mts-files
didn't have any metadata so I'm now creating time/date so they will be
properly added in my library.
However, the time will always be wrong in Shotwell, even though it looks
good to me?

When I import this file with Shotwell it reports
Date: lör 3 feb, 2001
Time: 2:14
So the date is right but the time is wrong. Why is this?
