Critical regression fix for convertTimezoneToOffsetStr:
Issues Fixed:
- Previous regex /^([+-]?\d{1,2}):00/ only matched :00 offsets
- This caused half-hour offsets (e.g., India +05:30) to return UTC+0
- Even if matched, parseInt only parsed hours, losing minute info
Changes:
- Update regex to /^([+-]?\d{1,2}):(\d{2})/ to match all offset formats
- Parse both hours and minutes separately
- Output format: "UTC+5:30" for non-zero minutes, "UTC+8" for whole hours
- Preserve leading zeros in minute part (e.g., "UTC+5:30" not "UTC+5:3")
Test Coverage:
- Added 8 comprehensive tests covering:
* Default/invalid timezone handling
* Whole hour offsets (positive/negative)
* Zero offset (UTC)
* Half-hour offsets (India +5:30, Australia +9:30)
* 45-minute offset (Chatham +12:45)
* Leading zero preservation in minutes
All 14 tests passing. Verified with timezone.json entries at lines 967, 1135, 1251.
- Fixed convertTimezoneToOffsetStr() that only extracted first digit
* UTC-11 was incorrectly displayed as UTC-1, UTC+10 as UTC+0
* Now correctly extracts full offset using regex and removes leading zeros
- Created reusable TimezoneLabel component with inline mode support
- Added comprehensive unit tests with 100% coverage
- Integrated timezone labels into 3 locations:
* Panel time picker (next to time input)
* Node next execution display
* Panel next 5 executions list
