Question / Feature request regarding localized time format

This may be possible, but I couldn't find it in the docs. I would like to display a time in a users locally preferred format—either 24h or 12h with am/pm. I tried `localizedFormat` with 'LT', but that gives me `1:36 PM` in the UK, where the preferred time format is 24h (as returned by `new Date().toLocaleString()`.

Is there a way to show a time _either_ as `HH:mm` or `h:mm a` depending on the user's locale / machine preferences?

Start by examining the localizedFormat plugin's handling of the LT token and compare it with the behavior of new Date().toLocaleString(). Determine how locale or machine preferences can select 24-hour versus 12-hour output, then add coverage showing the expected HH:mm or h:mm a result for each preference.
