Greptile Overview

Greptile Summary

This PR fixes timezone-dependent test failures by replacing local date methods with UTC equivalents in schedule test assertions.

Changes Made:

• Replaced getMinutes() with getUTCMinutes() in interval alignment checks
• Replaced getSeconds() with getUTCSeconds() in time precision assertions
• Replaced getFullYear(), getMonth(), and getDate() with UTC equivalents in date validation tests

Why This Matters:
The Croner library returns Date objects with UTC timestamps. When tests used local date methods like getMinutes(), they would return values in the machine's local timezone. In timezones with non-integer hour offsets (e.g., UTC+05:30, UTC+09:30), this caused minute values to be offset, breaking assertions that expected specific minute alignments (e.g., divisibility by 5 or 10).

By using UTC methods, the tests now correctly validate the actual UTC time values that Croner calculates, making the tests timezone-independent.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The changes are purely test-related and fix a real bug. All modifications convert local date methods to UTC equivalents in test assertions, which is the correct approach since Croner returns UTC timestamps. The changes are minimal, focused, and well-tested according to the PR description.
• No files require special attention
