Hello,

When I create an event by dragging, it always adds one hour to the start attribute.
After investigating the issue, it was due to daylight saving time and the way it's handled.

so if I write this in chrome console, for example:

new Date("2021-03-26 00:00:00")

it will print

Fri Mar 26 2021 01:00:00 GMT+0300 (Eastern European Summer Time)

as you can see, it auto-adds 1h as expected, but the package doesn't expect this.
