Netflix releases all their shows at 3 AM EST. Same for Disney+ and I think CBS All Access. Hulu is 12 AM EST, so is Apple TV+. Amazon Prime Video is unofficially 12 AM UTC.

Whatever the time is for each, these are outlets that release each and every show at the same time of day, so relying on individualized TVDB data for each show, which will often be incorrect, could be inefficient?

What got me thinking of this is TVDB, in their usual bureaucratic folly, has a policy to register 3 AM as the airtime for all shows on (U.S.-based) streaming services, despite the fact that it results in inaccurate data for many series, e.g. Hulu's.

This might also get around problems that arise from, for instance, a Netflix show having an origin country that's not the U.S. (maybe that's inherently incorrect but it happens with some shows from foreign studios), and Trakt assumes the 3 AM airtime to be in the region of that origin country, and not EST, which Netflix uses regardless.
