EpisodeActionReader created (or appended to) file actionreader.log in Nextcloud base folder (with index.php & occ). This concluded in a Nextcloud warning about "additional files in Nextcloud folder" in the self-check feature.
createDateTimeFromTimestamp interpreted 0 as timestamp as a mistake while 0 is a valid timestamp.
The fix checks if timestamp is null (not defined/initialized), so that 0 is treated as a correct timestamp.
Reverting the change of format of the timestamp that gets saved into episode_action table.
Reason: The 'T' was in there so that the timestamp format is like AntennaPod's timestamp format.
Use UTC timestamp for episode actions instead of the timezone used by the AntennaPod app.
Correct conversion should be assured because the AntennaPod timestamp includes a timezone identifier (T).
Also slightly change the output format for the DateTime-timestamp to equal other timestamp formats.
