Accuracy

Date-aware time conversion

Offsets are resolved for the local date entered, rather than treating the current offset as permanent. This matters around daylight saving transitions and when locations change rules on different dates.

The converter uses the IANA time-zone database available in the browser. A local clock time skipped during a spring-forward transition is reported as invalid instead of silently changing the requested time.
