The element currently render the hour format according to the local of the provided lang attribute, which when en or en-US will uses 12h clock format which is unexpected for users who are living in a region where the 24h format is the predominant format.

I therefor propose to render the hour format in the user's preferred format that they have set in their OS, as determinable by Intl APIs. Specifically DateTimeFormat() accepts a hour12 option and the option for this value is determinable via various means. There is also a newer hourCycle option which also supports the 11-hour format, but this API is not yet widely supported in browsers.
