Time zone and 24 hours time format

[tatata9999]

Hi,

What time zones tend to use 24 hours time format? Googling hasn't
been able to answer the question.

Thank you.

Everyone of even approximately normal intelligence can

Using 24-hour times in the U.S. is rare enough so the average person
probably won't know what it is.

If I had meant "does understand" I would have written that.

Perhaps you should be less ambiguous. ;)

The exercise will, or might, do them good.

That's an optimistic view, I think.

But surely the vast majority have come across "Military Time" being used
in the movies or on TV?

Someone not used to 24-hour times may know that is what they're seeing,
but if the goal is to be useful to the visitor, as in appointment
setting, then knowing what time it really is is what matters. No?

I think the relevant (for this discussion, albeit irrelevant for this
group) viewpoints have been put forth. In countries where a 24-hour clock
is used for exact times (as distinct from vague hour indications in a
colloquial setting where other time indications may be used), a 12-hour
clock is confusing -- and vice versa. So whoever writes software to be
used everywhere should allow all timezones and *independently* both time
notations.

BTW, there are more than two informal time notations. For instance, in
Swahili one would use "saa mbili" ("two hours") for eight o'clock in the
morning, counting from sunrise.

Most annoyingly are the TV announcements that say "Coming up at 9
o'clock..." with no mention of whether it is am or pm!

In the US, times are given as <time>, <time -1 hrCentral. For Pacific
time (California), they delay the programs and run them at <time>.

If you're in the Mountain Time zone, you just have to subtract two hours
from <timeto come up with when the show will be on.

What you need to do is go to the unicode.org Common Locale Data
Repository. It has the countries, and time format information you are
seeking.

Next, when a visitor comes to your site, you need to look at their
language preference string (Accept-Language header) and follow it.

For example, en_US is 12 hour, en_GB is 24 hour, while en_AU is 12 Hour.
Most other European countries are 24 hour.
