"and THEN...you get a call...from the astrophysicist." The arrival of an astrophysicist has never been so sinister.
-
This video should be called "Timezones - Tom Scotts descent into madness"
-
You know that your date calculator is accurate when it asks you: "start date, end date, location, ethnicity, political spectrum, belief system"
-
And to think, someone just asked Tom what time it was, then started recording.
-
"And you thank them for making it open source" - Best programmer line ever.
-
You forgot when France changed their calendar and tried to introduce decimal time.
-
And then you get a call from someone on Mars...
-
Then you get a call from a space station in close orbit around a black hole, saying that their seconds are slower than Earth seconds, and ask you to add code to account for that.
-
And THEN, you get a call from your boss, asking if you can work tomorrow
-
You forgot to mention the phone call from a Swedish historian talking about the years from 1700 to 1712, which ended up with February 30 1712 being a real date in Sweden.
-
Then you get a call from Arizona saying "Oh we don't do Daylight Savings Time." And then you get a call from the Navajo in Arizona saying "Oh we actually DO do Daylight Savings Time."
-
I am currently writing timezone code. EVERY WORD OF THIS IS TRUE.

Nice overview, but Computerphile forgot to mention how Sweden in 1699 decided to adopt the Gregorian calendar gradually over a 40-year period – and managed to butcher the plan already the next year. In fact, the period 1699-1753 in Sweden comes with many surprises. For example, Karl XII decided to switch back to the Julian calendar in 1711. http://en.wikipedia.org/wiki/Swedish_calendar

I like how the Astrophysicist is the breaking point when ironically those are the only people with justifiable reasons for making modifications in time recordings, while the rest of the world's is just like... "We do this, so accommodate us"
-
"So it was two hours ahead of Greenwich despite having Greenwich" LMAO It killed me xD xD xD
-
Don't worry about timezones, worry about why all these people in all those countries know your number :D
-
I can see Tom Scott's hair turn grey, or gray (depending what time zone you're in) during the duration of this video.
-
"and you never ever look at it again because that way lays madness"
-
Did anyone else just kind of enjoy watching Tom getting progressively more stressed?
-
This was the greatest rant I have ever heard
