### What changes were proposed in this pull request? The `DateTimeUtilsSuite` and `TimestampFormatterSuite` assume constant time difference between `timestamp'yesterday'`, `timestamp'today'` and `timestamp'tomorrow'` which is wrong on daylight switching day - day length can be 23 or 25 hours. In the PR, I propose to use Java 8 time API to calculate instances of `yesterday` and `tomorrow` timestamps. ### Why are the changes needed? The changes fix test failures and make the tests tolerant to daylight time switching. ### Does this PR introduce any user-facing change? No ### How was this patch tested? By existing test suites `DateTimeUtilsSuite` and `TimestampFormatterSuite`. Closes #26273 from MaxGekk/midnight-tolerant.
