I have been meaning to get back on this, but not sure if I should post it here or in bug thread.
I thought creating a “DATE_FORMAT_LC4” override in the language settings solved my issue but it does not (almost) the override does work, but it also shows the 24 hour time.
my override is: DATE_FORMAT_LC4 D F d, h:i a
and the output is: Mon April 7, 08:45 pm 20:45
it may be hard coded somewhere in your component to display that last piece of time, if it could use just the LC4 format that would be swell
