Description Alex 2025-05-19 08:44:57 UTC 
SUMMARY
When importing a csv file (from ie datalogger) in LabPlot there are many options for date formats to use but no option for a Unix timestamp format. Many (industrial) PLCs/logging devices uses this format as standard and would be nice to have the option to convert at import without manipulating the csv first. 

STEPS TO REPRODUCE
1. Have a csv file with ie logging data and one of the columns to be timestamp in unix time format
2. Import this file in LabPlot and attempt selecting correct time format for the date/time column
3. 

OBSERVED RESULT
No option for Unix Time format

EXPECTED RESULT
To be able to select the widely used Unix Time format

SOFTWARE/OS VERSIONS
Windows: Windows 10
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)

ADDITIONAL INFORMATION
This issue/question was also posted in the discuss forum: https://discuss.kde.org/t/convert-unix-timestamp/34238
Currently the workaround is to manipulate the csv file ahead of import
