 |
|
Hi and thanks for reading this!
I run a stable amd64 box with systemd instead of openrc. As advised by systemd itself, my hardware clock is set up to UTC:
| Code: | $ timedatectl
Local time: sáb 2017-04-01 12:24:15 CEST
Universal time: sáb 2017-04-01 10:24:15 UTC
RTC time: sáb 2017-04-01 10:24:13
Time zone: Europe/Madrid (CEST, +0200)
Network time on: yes
NTP synchronized: yes
RTC in local TZ: no |
My DSLR is correctly set up to current local date and time (Central European Time, or UTC+2:00). Yesternight I shot the sky and the last photo was taken at ~23:29 local time (21:29 UTC + 2:00). Gwenview correctly reads the original date is 23:29 from EXIF data, but both Dolphin and Konsole show the date as if the picture were taken two hours later, i.e., next day at 01:29:
| Code: | | -rw-r--r-- 1 user user 8385454 abr 1 01:29 P3310855.JPG |
Why is that? What config should I check? I'm clueless.
Thanks again. |

I highly doubt this is a systemd issue and likely would happen with openrc as well.
What are you using to copy the files from the camera to the computer - is it a PTP/MTP or mass-storage, I'm not familiar with gwenview.
If you pull the media (likely FAT16/FAT32 which has no idea about timezone) from the camera and stick it into a discrete cardreader, you should see the date that most copy programs will use. Most programs do not timestamp the file with the EXIF time, only the filesystem time...
Historically FAT16/FAT32 times are always localtime unless you use otherwise - matching what DOS machines used in the past. However a lot of hardware play fast and loose with these timestamps so they're not really standardized anymore...
