pickadate widget doesn't use the correct 24h format in some languages

[vincentfretin]

BUG

See https://community.plone.org/t/datetime-widget-format-not-am-pm/12491

What I did:

Plone in French language, create a Page, click on the Dates tab and pick a date.

What I expect to happen:

In French and Norwegian, the hours should be in 24h format, so showing 17:27 in the afternoon.

What actually happened:

It shows "05:27 p.m." instead of "17:27"
Note, in German, which uses 24h format too, it works properly.

in French

in German

What version of Plone/ Addons I am using:

Plone 5.2.2rc1

[vincentfretin]

In German, the page source contains

data-pat-pickadate="{..., "time": {..., "format": "HH:i"}}"

in French:

data-pat-pickadate="{..., "time": {..., "format": "h:i a"}}"

but this really should be like German.
Where is the format configured?

[vincentfretin]

Oh my, for German, we have the following translation in plone.app.locales/plone/app/locales/locales/de/LC_MESSAGES/plone.po

#. Default: "h:i a"
#: plone.app.widgets/plone/app/widgets/utils.py:72
msgid "pickadate_time_format"
msgstr "HH:i"

So that's it @espenmn @zopyx

We can edit the date format too!

#. Default: "mmmm d, yyyy"                                                      
#: plone.app.widgets/plone/app/widgets/utils.py:59                              
msgid "pickadate_date_format"                                                   
msgstr "mmmm d, yyyy"

I don't know who translated these two strings in French by just copy and paste but it wasn't me, at least I don't remember :)
