Fullcalendar slotLabelFormat does not change with Locale

[SushmaShashidhar]

It is mentioned in the fullcalendar document here that slotLabelFormat takes Locale into account.
https://fullcalendar.io/docs/slotLabelFormat

But this is not working. If we set the Locale to German (de-DE), which has time format as H:mm (24 hours), the slot label still appears in 12 hours format which is the default (h:mm) .
This can be tested by setting locale to de-DE

There's no locale named "de-DE", but the locale "de" shows the labels in 24 hour format in this demo:

Would you be able to post a runnable, stripped-down demonstration of the bug? Would really appreciate it because the time saved reproducing will be time spent fixing.

Hi,

Please see below de-DE is one of the locales. I see quite a few locales are missing in the demo link you have shared.

The locales come from Moment.js, so if there is something specific to "de-DE" compared to the "de" locale you should submit it there, otherwise use "de" for the locale.
