Maybe I'm looking at this wrong, but if you examine the episodes I marked watched today at https://www.tvmaze.com/users/22366/louiswu/watched, they are not in chronological order. I grabbed the actual timestamps to make sure there was no conversion problem. (lists below are [timestamp] [episode id] [episode name] [translated stamp])
It shows as follows:
1620504819 2038023 star-wars-the-bad-batch-1x02-cut-and-run May 8, 2021, 8:13:39 PM UTC
1620491804 2038022 star-wars-the-bad-batch-1x01-aftermath May 8, 2021, 4:36:44 PM UTC
1620508197 1399069 air-crash-investigation-17x01-deadly-airspace May 8, 2021, 9:09:57 PM UTC
1620466157 1399070 air-crash-investigation-17x02-blown-away May 8, 2021, 9:29:17 AM UTC
1620466157 1399071 air-crash-investigation-17x03-nuts-and-bolts May 8, 2021, 9:29:17 AM UTC
Where this would make more sense:
1620508197 1399069 air-crash-investigation-17x01-deadly-airspace May 8, 2021, 9:09:57 PM UTC
1620504819 2038023 star-wars-the-bad-batch-1x02-cut-and-run May 8, 2021, 8:13:39 PM UTC
1620491804 2038022 star-wars-the-bad-batch-1x01-aftermath May 8, 2021, 4:36:44 PM UTC
1620466157 1399071 air-crash-investigation-17x03-nuts-and-bolts May 8, 2021, 9:29:17 AM UTC
1620466157 1399070 air-crash-investigation-17x02-blown-away May 8, 2021, 9:29:17 AM UTC
Thanks, Louis :)
