1.8.2 Event scheduling

I have to create an event that is repeated every hour, but I am from this error

if I enter the date from DataPiker then I see the date as follows: / December / 1899189918991899

how can I do?

XIBO 1.8.2

Could you tell me what do you have in CMS Settings -> Regional tab please? (date format specifically)

That is the problem then, please change the date format to d/m/Y H:i
Italian language is also just it

after the changes here is the result
You can not set the end time before the start time
