// Adjust time when it's coming from DST

Hi
can you explain why you add one hour to the date when the next day has a DST change? Isn't the parse value wrong then?

I put together a stackblitz example:
https://stackblitz.com/edit/date-fns-playground-grl7an?file=app.ts
Notice the dates after 2019-10-26 01:00
e.g.

parse 2019-10-26T06:15:00+02:00:     Sat Oct 26 2019 06:15:00 GMT+0200 (Mitteleuropäische Sommerzeit)
parse 2019-10-26T06:15:00:  Sat Oct 26 2019 07:15:00 GMT+0200 (Mitteleuropäische Sommerzeit)

My current timezone: CET

I'm facing the same issue, parsed dates on the 26th of October are off by one hour.

Same issue: Seems to be introduced with #1003 / #1005 - it takes the next day into consideration with those changes.

Wrote a comment there first then saw this issue: #1003 (comment)
