Today, I started a project to link the paradata with the audio audit files. From what I can tell, the time stamps in the paradata are in UTC (timestamp_utc, with the offset provided in tz_offset) while the audio audit files are in “raw” tablet time (i.e., time taken from the tablet and expressed in local time, rather than in UTC with an offset).
The paradata docs are clear: it’s in UTC. Meanwhile, the audio audit docs are open to interpretation but lean towards an understanding that the timestamp is in in local tablet time:
The timestamp included into the name of the file indicates the beginning of the recording session. Provided that there were no adjustments to the device clock, the audio recordings should be replayed in the chronological (increasing) order of the timestamps.
Is this that understanding correct? Are these time stamps expressed in different time terms–UTC for paradata and local time for audio audit files?
