@infograf768 according to the code: https://github.com/joomla/joomla-cms/blob/staging/media/system/js/fields/calendar.js#L540-L544
shift + enter is the enter equal (accept value and enter is the same as escape. I don't remember why we did it like this

@dgt41
Enter alone works for en-GB

Tried shift enter and tab => same result

Also, if the Publishing field is empty for example, when i choose today, it does not save here at all. Field is saved empty

"Enter" acting as "Escape" certainly is wrong and unexpected behavior. "Shift-Enter" is basically a useless combinations since there is no hint that we can use that ?

@Bakual I don't remember the exact reason but had to do with the ability to keep the manual input of text in the field, you might remember that discussion...

The other issue when field is empty (Publishing field)

Nope.

Hi
This problem arose in joomla 3.7
After the digit were written in Persian
I also can not manually enter a date
There was no such problem in joomla 3.6, which was the English digit.
Now for choose another day before today, i should first choosing hour and then choose the day.
but after change any digit, date reset to today

I have change digit in media/system/js/fields/calendar-locales/fa-ir.js from persian to latin

but problem not fix, then replace media/system/js/fields/calendar.min.js by same file in joomla 3.7 package, and some problem fix

Closing as we have a patch #16794

Calendar always saves seconds like ":00"

1. If select TODAY in datepicker set date and time as 2017-06-29 04:17:47 but after save replace date and time as 2017-06-29 04:17:00
2. Always save article with seconds like ":00"
