Hi! Our team is spread across timezones, and we have found applications that either - only show "current times" (doesn't help us schedule as much) - broken (the 2 apps that showed up on slack for timezone support, showed wrong times for teammates.) and many apps I've found through this subreddit are also broken (such as timezone.io).
