Was this PR generated or assisted by AI?
NO (Only the manual test case for America(Los_Angeles) timezone was created by AI to verify the fix.)
Purpose of the pull request
Fixes #18015 DST issue when calculating $[yyyyMMdd±N] time placeholders.
Day-based calculations were previously implemented in minutes, which caused incorrect dates during Daylight Saving Time transitions.
Brief change log
1- Replaced minute-based day calculations with addDays for expressions like yyyyMMdd+N & yyyyMMdd-N.
2- Ensures correct date calculation in timezones with DST (e.g., America/Los_Angeles).
