About this video

Tom Scott explains for Computerphile why handling time and timezones in code is so hard, walking through a simple web app that computes how long ago something happened. It covers the quirks of timezones and calendars and ends in an exasperated rant.

Why it appears in the archive

It is the go-to funny, accessible explanation of why you should never implement datetime handling yourself, linked in nearly every timezone thread.

This will probably resonate with people here[1]. A brilliant video by Tom Scott for Computerphile, where he starts to explain what coding timezones correctly is like and by the end of it is in full polite-mini-rant-mode :D [1] [VIDEO]

Computerphile did an excellent overview of time zones and all their complexities in the context of programming: [VIDEO] I was quite surprised by some of the stranger rules out there, especially the regions that chose to skip a day for whatever reason. Timezones are complex! Far, far more complex than simple offsets.

>Just try to explain to everyday people just how hard the problem is A bit off topic but Computerphile / Tom Scott did an excellent video doing that [VIDEO]

I really enjoyed this. And I think no one mentioned the very related Computerphile video yet: "The Problem with Time & Timezones " [VIDEO] Same topic, equally entertaining (not AS geeky though).

> such a reasonable, trivial task? Tom Scott has a pretty good video explaining exactly why writing code about time is not trivial: The Problem with Time & Timezones - Computerphile [VIDEO]
