    That 00:00 is probably the result of some simple formatting rule: if "hours" is less that 10, add a leading '0'

    Regarding Michael R's thought provoker, strictly speaking, a colon in a time implies a 12-hour clock, meaning that 1:00 is not a proper time as it's lacking AM/PM. For 24-hour clocks you should use "h" between the hours and minutes and values less than 10 should lead with a zero, meaning that "14:00" is also an invalid time, but 01h00 and 14h00 are valid.

    The reality though is that it's very common that people don't know (or care) about these rules meaning that we're all pretty regularly having to deal with ambiguous representations of time. Still not quite as bad as backwards people (and even a few backwards countries) which write their dates as MM/DD/YYYY.

    I was so hoping the Garmin 280.097 feet was a nice round number of meters. It isn't. Neither a nice round number of furlongs. Nor rods, nor statute, nor nautical miles. Color me disappointed.

    As to the mystery of zero hours, I think the best part is that they express the same time as "0:00" and "00:00" in different spots. Pick one and stick to it please. Idjits.

    Having lived all my life in a "24 hours clock" country, I never heard of these rules, and have never seen time as "01h00" except in France. Any sane country uses a hh:mm format: 00:00 - 23:59. And sometimes the prefix 0 is skipped, so 1:00 is used as well in a 24 hours notation.

    The WTF in the story is I see it, is that both 1:00 and 01:00 are used on the same page.

    A thing with the "h notation" is that it is sometimes used to indicate duration, but with an additional "min" for minutes: "2h25min" for 2 hours and 25 minutes, but "2:25" or "02:25" can be used for the same purpose, or for 2 o'clock (during night) and 25 minutes. As mentioned, the prefix "0" for hours is optional, some digital clocks display it, others don't. Same applies whe shifting from "hours:minutes" to "minutes:seconds"; the first element can have a padding zero, all subsequent ones must have one (so no "2:5" or "14:7").

    puts pedantic hat on puts probably wrong hat on as well

    Hmm, isn't 00:00 midnight at the start of the day?

    If they meant the end of the day they should have used 24:00 or avoid confusion and use 23:59.

    Of course ISO8601 specifies a data transmission / interchange format, NOT a UI display format.

    Lookup the unicode CLDR, using colon to format 24-hour time is not only correct, but THE correct way on a lot of locales, I'd even say for the majority of them. For example, here's the entry to en-GB: https://st.unicode.org/cldr-apps/v#/en_GB/Gregorian/279c95c24026a2f3

    There's no reason to be rude about it, implying that France is somehow insane for writing "quatorze heures cinquante" as 14h50. The slightly loopy part about it in France is that what you'd probably insist should be written always as 14:00 is sometimes 14h00 and sometimes just 14h.

    Oh, and beware of the meaning when someone in France describes something as happening in the "am" - that person almost certainly means "après-midi" == afternoon, not "ante-meridian" == before noon.

    I should've read all posts, before replying I guess. Goes to show, regional formatting is hard ;)

    "A few" backwards countries use MM/DD/YYYY? AFAIK only one.
