Audio import shows wrong date #215

Closed RichardLitt closed 1 year ago

RichardLitt commented 1 year ago

I am having some issues importing audio set in GMT format with the right time stamp. 

    - name: Queens
      description: >
         Recording station in a Queens apartment building near this park.
      time_zone: US/Eastern
      latitude: 40.75
      longitude: -73.91
      elevation: 32

Recording names:

Recordings/Queens_20230502_010000_Z.WAV Recordings/Queens_20230502_033000_Z.WAV Recordings/Queens_20230502_060000_Z.WAV

The timestamps in Vesper are not switching to local, EST, time. Any ideas?

Thanks for pointing out this issue. To specify UTC times in recording file names, you currently must use names like "Queens_2023-05-02_01.00.00_Z.WAV", i.e. with dashes in the dates and dots in the times. The form you tried gets handled by an outdated MPG-Ranch-specific parser that interprets the "Z" as a comment instead of as a time zone indicator, and so interprets the time as local instead of UTC. I will aim to support the form you tried in the near future, and have created issue #216 for that task.

Thank you! Let's close this for now, then. However - the note in https://vesper.readthedocs.io/en/latest/tutorial.html doesn't say that you need this. Should we update it? I'm not sure how I can.

Good idea. I've updated the note.
