I marked a movie as watched on Trakt on Oct. 29 at 8:11 PM, and I see the correct date and time in Trakt, but Moviebase is displaying the watched date and time as Oct. 30 at 12:11 AM.
I confirmed this is an issue when marking a movie as watched within Moviebase as well. If I mark a movie as watched, Moviebase initially shows the correct date and time and Trakt shows the correct date and time as well. But when I close and reopen Moviebase, and it syncs with Trakt, the time within Moviebase is ahead by 4 hours.
