Every sundial is a 24-hour sundial. Every. Single. One.Recusant said:try and build a 24-hour sundial if you disagree.
This... this very much. Especially when I am tired and a mate asks the time and I forget to switch the filter on... 'Oh, it's twenty three hundred hours.'Jark212 said:Well ,i'm in the military so i tend to use a 24 hour clock for everything, even if I have a 12 hour clock I'll just automatically convert it in my head. It gets kinda annoying when my regular friends ask me what time is is and I tell them it's 1430.
all those weird looks...
Germany uses 24h almost exclusively.zumbledum said:isnt this pole pretty much are you an american civilian , or anyone else in the world? never heard of any other country using the 12 hour clock
yeah thast my point the entire world does, except America where they call it military time i believe because the military uses 24h clock to , so its literally just american civilians left.mjharper said:Germany uses 24h almost exclusively.zumbledum said:isnt this pole pretty much are you an american civilian , or anyone else in the world? never heard of any other country using the 12 hour clock

Already discussedSuperSuperSuperGuy said:I use 12 hour most of the time, simply because that's what I'm used to, but I can work with 24 hour if I need to. I like the 24 hour system, don't get me wrong; it makes much more sense than using each time twice a day. However, I've been using the 12-hour clock since I was a little kid, and I don't see enough of a practical difference to justify permanently switching over.
Also, is that 30-hour clock seriously a thing? How does it work? Do they shrink the hour such that 30 of them fit in a day, or something?
DoPo said:24:01 and forward is an unofficial standard (at least I think it's unofficial, I can't remember ISO 8601 mentioning it or anything else big) for times after midnight. 0:00 is midnight start of today and time progresses until 24:00 which is end of today or tomorrow's 0:00. These are part of ISO 8601 - 24:30 is, not often, but often enough to be semi-official notation to mean "half an hour after today". Similarly, 27:00 would be "three hours after today" or "three o'clock tomorrow". It's used to unambiguously distinguish between two times if you need to roll over a new day during the operation. So, for example, if you start a log on, say, the 10th of the month, if you were to note something happening at 27:00 it's unambiguous whether you mean 03:00 on the 10th or 03:00 on the 11th, as opposed to, you know, using 03:00.Zontar said:It's more of a joke in reference to the fact that Japanese broadcasters use 24:00-29:59 instead of 0:00-6:00 between midnight and 6am. I don't know if anything else uses it though.
It's just that there aren't that many situations that require the post-today notation, so it's not that widely used. It's definitely out there, though.
