Command --get-all-files with --filename=%Y%m%d%H%M.jpg returns a datetime that is 3 hours later than system time

[ioulosve]

Hello, I'm trying to investigate this problem.

I have a Canon EOS 1200D connected to a raspberry and set up to take a picture every hour.
The raspberry time is set to UTC and I'm saving the pictures on the SD card with the following command:

gphoto2 --filename=%Y%m%d%H%M.jpg --get-all-files --skip-existing

The pictures are saved correcly but the resulting filename is always 3 hours more than raspberry time. For example, if the picture is taken at Wed May 29 09:33:19 UTC 2024, the filename is 202405291233.jpg.

My question is, where do gphoto2 takes the time information? Does it take it from the camera? How do I fix this issue?

Thank you
