Schedule time is offset by 1 hour during switch to/from daylight saving time

[jtyner]

In the United States, daylight saving time ends this weekend.

When scheduling a post to be published next week, after DST ends, the schedule time of the post as reflected in the schedule settings is offset by 1 hour from the time the user selects. Posts scheduled before DST ends show the correct schedule time.

For example, a post scheduled for 5 a.m. on Tuesday shows a schedule time of 4 a.m. instead.

This is an unexpected behavior for users. I think it would be a more intuitive experience for the post to schedule at the time the user selects.

Btw, this issue seems like it might be similar to #12610, which was closed in 2010.

Hi! I think this was the same issue reported in
​https://github.com/WordPress/gutenberg/issues/46333

If so, the bug should be fixed, and the ticket can be closed as 'reported-upstream'. If the bug still occurs, it probably would need to be reported again in the Gutenberg repository.
