indicator-datetime ignores 12/24 setting for other locations

[Reece]

indicator-datetime shows "auto-detected locations" and "other locations" in 12h format, regardless of 12/24 setting. See attached image that clearly shows time as 24h in the top panel and and as 12h alternate locations. (Time zone setting is UTC in the screenshot, but the symptom occurs for other timezones.)

I've used 24h and alternate locations for years and I would have thought I'd have noticed previously.
