Inconsistent/incorrect time formats

Problem

Time formats seem to vary inconsistently between languages.

• When language is set to UK English, 24-hour time incorrectly has no leading zero
• When language is set to Croatian, 12-hour time incorrectly has a leading zero

Across all languages, time formats are displayed arbitrarily differently, unrelated to the conventions of the language it is set to. For example: Spanish (Spain): '2:30 p. m.' Spanish (Latin America): '2:30 p.m.' With Time Format set to '24-hour'; Language set to 'English': image Language set to 'English (US)': image Dates are inconsistent too. For example, Croatian has a space between the day, month and the year. (Perhaps this is LLM localisation weirdness?)

Proposed solution

Don't localise times. Apply a consistent format across languages.

• 24-hour should have leading zeros and a colon as the separator.
• 12-hour should not have leading zeros and should have a colon as a separator, with 'AM' and 'PM'.

It also makes sense to give users the option of switching between DD/MM/YYYY, YYYY/MM/DD and MM/DD/YYYY independent of language. As human localisations come in, formats can be properly localised. For example, using Japanese kanji in the date format (2023年12月31日).
