[php-src] Issue #8432: Incorrect DST Calculation in Intl

Issue: https://github.com/php/php-src/issues/8432 Comment Author: jimbo2150 If I were creating a new date with that time, I would agree. But it's going from March 13 prior to the DST change to a date after. Seems a bit strange that adding hours specifically would account for the change while adding a day does not. They both cross a DST boundary and seems like they should both account for it. Also don't think the majority of people are going to think, I need to add a month, let me calculate that in hours and add it to make sure DST is accounted for... No, they will just add a day, a month, etc. and end up with the wrong time (unless they are also changing a time value along with a day/month value).
