So @sotolf reminded me of something I kind of love. The Japanese "30-hour system". Used in nightlife, broadcasting, and transport, the time extends the day past midnight to keep late-night events grouped with the same calendar day. So a club open from 11PM to 1AM might list its hours as 23:00–25:00.

We should all adopt this!

Sadly Wikipedia does not have a detailed page on this system in English but here is a little longer explanation:

I was told by a colleague that NASA sometimes use extended hour formats (like 25:00 or 26:00) to keep events grouped on the same operational day. So it is kinda the same as the Japanese 30-hour system. I cannot find a great article on this but if someone knows of one, let me know. 😉

But that's Nasa...

"Endeavour, you are go for throttle-up to 104%".

Why? Because when they upgraded the shuttle engines, they couldn't be bothered to update the manuals and checklists, so everything is still in percent of maximum power of the original engines.

@leeloo LOL, love it!

@leeloo 😱

@leeloo @ruari Apropos high percentages, for I think it was baker recipes, they also often go way over 100% since 100% is the ingredient with the highest amount, like flour, and then other ingredients like salt gets 3% etc, so that it's easy to adjust the recipe, that's pretty nifty :)
