A web app that works out how many seconds ago something happened. How hard can coding that be? Tom Scott explains how time twists and turns like a twisty-turny thing. It’s not to be trifled with!

  1. i have never cared much for time zones, i have never been in a situation in my life where different time zones has affected me aside from talking to someone on the other side of the world and figuring out when is the best time to contact that person, but this video was presented so well, that it was both informative and entertaining… you just earned a new sub!

  2. i need to ask some that is i was doing my work in GMT+5 while uploading that folder then timeZone of that folder automatically change to the current timezone but the time zone of the file will remain the same . can you please guide me why it happened ?
