In Audacity, name the track with the time (California time) appended to the track name in the format hh-mm-ss.
For example: “Koz’s long recording 22-00-00”
Then click on the track and generate labels with this new plug-in: Labels to show time that a recording was made
Let me know how it goes, and if the times do anything weird (writing this plug-in was not as easy as I anticipated - Nyquist is not the easiest language for parsing text).
