I find this last sentence hard to understand (before and after this change).
I think this retains the meaning:
For any given
time_zone, it is possible that there is notime_pointthat returns asys_infonot on daylight saving time. If such atime_pointdoes exist, it is guaranteed not to be in the range [begin,end) of anysys_infoon daylight saving time.
I also think "querying the time_zone could be more precise, by referring to the get_info member.

I think any such larger rework is for C++23. Added to #4340.

@jwakely If you're happy with the suggested approach (this change for C++20, something else for C++23), please can you approve or merge this PR?
