"used occasionally in some special contexts such as broadcast TV" is not what I'd call fairly common! Never encountered it in half a century here, just military time "0 3 hundred" as used on the shipping forecast, or simply 3am.

It’s extremely common in Japan. Literally everywhere.

Never seen it in the UK.
