I have my website set to fr_FR, the settings for EA calendar is fr and time format set to 00-24.
After selecting an appointment, the bootstrap form displays the date/time in the wrong format.
For example, November 17th at 11 am is displayed :
17 November 2017 11 hh 00 MMmmM
The month is in english (in french it’s Novembre, not November) and the time should be 11 h 00 (one h and no MMmmM at the end).
