SUMMARY
Timestamp not updated when using File name timestamp
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
I am trying to change the modified timestamp of a file named "VID_20210819_093309_00_426.mp4". I use the batch processor with Timestamp used = File name timestamp. I don't see any result. I also can't find documentation what the format of the filename should be for this feature to work.

STEPS TO REPRODUCE
1. Load file wit filename VID_20210819_093309_00_426.mp4 in batch processor;
2. Select in Control Panel Metadata | Time Adjust;
3. Select in Time Adjust screen Timestamp used = File name timestamp and Timestamp updated = File last modified
4. Execute batch

OBSERVED RESULT
File last modified timestamp not changed

EXPECTED RESULT
File last modified timestamp updated to date = 2021-08-19 and time = 09:33:09.00

I can not reproduce, works without problems. Note that you have to activate the "overwrite automatically" option under Behavior, otherwise a new file will be created to which the changes will be made.

Ok, that particular date format in the filename fails. Strange, since it's actually nothing special. I have a look at it.

Comment 4 Maik Qualmann 2022-03-29 05:57:22 UTC 
A note: The Time Adjust Tool is also available as a standalone tool in the Item menu. It is more suitable for adjusting the time than in the BQM. In the standalone tool there is also a preview of the resulting timestamp.

Hi Maik,

Thanks for the tip.

In the items menu the date of "VID_20210819_093309_00_426.mp4" is read correctly from the file name. However, the time is set to 00:00:00.
Comment 6 Maik Qualmann 2022-03-29 06:41:56 UTC 
No, the date is not correct, check the year.

Comment 7 Jan van Bekkum 2022-03-29 07:25:47 UTC 
What is wrong with it? I read it as 2021-08-19 09:33:09.00
Comment 8 Maik Qualmann 2022-03-29 10:30:02 UTC 
This date file name format was still unknown for the function. When creating the function to decode date file names, we received a lot of samples from users. This format was not included. Now it is also recognized.

"Now" means version 7.7.0?
