Two clock faces rather than one, because a single analogue face can't tell you whether it's morning or evening — whichever half of the day isn't current is greyed out, and the figures underneath give the unambiguous 24-hour version. The left/right arrows move by one minute at a time, so you can land on any exact time.
Thai has a genuinely different system worth knowing about: the hour-word changes shape four times across the day (dtee for 1–5am, ...moong-chaao for 6–11am, baai...moong for early afternoon, ...moong-yen for early evening, and ...thum from 7pm on), and the hour-count itself resets partway through some of those instead of counting straight through to 24. German and Croatian both have their own classic trap too — halb sieben and pola sedam both mean 6:30, not 7:30, since they count the half-hour as “halfway to seven,” not “half past six.”
This is a good-faith build, not checked by a native speaker yet for any of the five non-English languages — treat the wording as a solid first draft, not an authority, especially for Thai.
