Major City to London Routes
How it works (technical)
- Parse user input (city name, code, or IANA zone) and normalize to an origin IANA identifier (America/Los_Angeles).
- Convert the chosen instant to UTC internally, then apply Europe/London rules to compute the destination local time and offset.
- Evaluate DST from the destination zone so displayed times reflect seasonal changes and transition edge cases.
- Render multiple output formats and friendly segment labels from the same underlying instant for consistency across the UI.
