Original timestamp can be valid and rounded-to not. Let's take an example from [date.h docs](https://howardhinnant.github.io/date/tz.html#nonexistent_local_time): ``` 2016-03-13 02:30:00 is in a gap between 2016-03-13 02:00:00 EST and 2016-03-13 03:00:00 EDT which are both equivalent to 2016-03-13 07:00:00 UTC ``` If we start with a valid `2016-03-13 00:01:00 EST` and ceil it to 2h30min, then the local time will fall into nonexistent gap. -- This is an automated message from the Apache Git Service.
