Timezone Convert

by AgentUtility.ai in Documents & files

x402 APIPassing, checked 1 h ago

Converts a datetime from one IANA timezone to another with correct DST handling. ISO-8601 input: bare wall-time strings are interpreted in the from_tz, fully-qualified offsets are honored. DST is handled correctly (uses V8's built-in tzdata via Intl.DateTimeFormat). Returns both formatted strings, both UTC offsets, and the difference in hours. Use it for DST-aware time arithmetic, wall-clock to UTC conversion, or converting across cities.
