Problem with date class and daylight savings

Hi, think there’s an issue here.

I have a date time set at:

30 Oct 2022 12:00:00am:

and then I add a juce::RelativeTime::days( 1 )

this then goes to:

30 Oct 2022 11:00:00pm

as I’ve added a full day I would expect this to go to:
31 Oct 2022 12:00:00am:

even though it’s crossed the daylight savings time barrier.

or is my thinking faulty here?

Thx, Lee
