Daylight savings time option

[MrARM]

Is your feature request related to a problem? Please describe.
Specific timezones have DST. Not all. While we can manually update this what if we automate it.

Describe the solution you'd like
When one of the dates occurs, set the hour back/forth.

Describe alternatives you've considered
Manually setting DST. Possible but we can do better.

Additional context
Testing will require some additional work. Keep in mind you will need to manually set the date on the RTC to one of the forementioned dates.
US and EU use different dates, so 4 menu options will be needed.
An EEPROM slot will also be needed to store this information.
