Time Converter

The tool provides DST-aware time-zone conversions and optional duration calculations for cross-regional planning. It accepts a source time, a source zone, and a target zone, with an optional date to resolve DST transitions. Conceptually, it maps the local time to UTC and then applies the target zone offset to yield the converted time. It supports optional duration calculations by accepting a second time or duration, returning a difference in hours (and minutes) when requested. Users include developers integrating scheduling logic, travelers coordinating meetings, and operations teams that log activity across zones. Its unique value lies in DST correctness, explicit handling of ambiguous times, and clear outputs including the offset in use and any rollover to a different date. Core features include input validation, DST-aware conversion, ISO 8601 formatting, and optional duration metrics. Typical use cases cover international team planning, customer support scheduling, and travel itinerary synchronization. The approach emphasizes deterministic results and avoids manual calculations that are error-prone, especially around DST changes and date-boundary crossings.
