All the shows are from Japan and I believe they do have TMDB country and IDs set up correctly. In addition, the airtime on trakt.tv seems correct for all of them but one.
To avoid further conversion, I adjusted the timezone on my phone to Japan Standard Time
D4DJ: First Mix (/shows/d4dj-first-mix/)
It is supposed to be Fri 23:00 but on SeriesGuide it is Fri 01:00
Is the Order a Rabbit? (/shows/is-the-order-a-rabbit)
It is supposed to be Sat 21:30 but on SeriesGuide it is Sat 15:30
The Gymnastics Samurai (/shows/the-gymnastics-samurai)
It is supposed to be Sun 01:30 but on SeriesGuide it is Sun 19:30
Adachi and Shimamura (/shows/adachi-and-shimamura)
This show just does not have an airtime on both trakt and SeriesGuide, can I assume it is a problem on trakt’s side?
As you can see, the difference between the expectation and the actual value is kind of all over the places
