1 hour offset when using UTC timezones that have Daylight Saving Time in DateTimePicker

**Describe the bug**
If I am using the Material UI DateTimePicker https://mui.com/x/react-date-pickers/ and have my timezone as Europe/London or Europe/Lisbon, the moment I click on the calendar date I get an offset of 1h on my timestamp https://codesandbox.io/p/sandbox/3w6yfw but no offset at all if I only click directly on hour or minute. Also, the bug doesn't occur on UTC timezones that do not use Daylight Saving Time such as Africa/Lome or any other timezones.

I have also created this https://codesandbox.io/p/sandbox/datepicker-forked-jygfn7 with Luxon to find out where the bug is coming from and had no offset issues.

**Expected behavior**
No offset when I click on the DateTimePicker calendar day while using DayJs.

**Information**
