wrong start time in JLS #37

Open WeiminWangKolmostar opened 2 months ago

WeiminWangKolmostar commented 2 months ago

I use both the https://github.com/jetperch/pyjoulescope_examples/blob/main/bin/capture_jls_v2.py and https://github.com/jetperch/pyjoulescope_examples/blob/main/bin/capture_jls_v1.py scripts to capture samples to a JLS v1 & v2 file, when I load the JLS files in joulescope GUI client, it always shows the sample start time is 2018-01-01.

Hi @WeiminWangKolmostar and thanks for creating this issue. The UTC time is a newer feature that never made it into the pyjoulescope binding. If you want this feature today, I recommend using:

python3 -m pyjoulescope_driver out.jls

You can provide the --help argument for more details about the available arguments.

Regarding the reported issue:

  1. JLS v1 does not support UTC time and never will. JLS v1 is also deprecated.
  2. JLS v2 does support UTC time, but JlsWriter in pyjoulescope does not. We will keep this item open.
  3. For the time being, you can use pyjoulescope_driver instead. Both the record entry point and record module add UTC time correctly.
