Measured tools (5)

• get_current_time read-only

  Get the current local time (or the time at a given instant) in one or more locations. Each location is a city name, an IANA timezone / abbreviation, or coordinates. Up to 50 locations. Results include a source_url linking the matching worldclock.pro page when available.

  Parameters:

  • locations (required) — array
  • at — string — Optional ISO 8601 instant to evaluate instead of now (read as UTC if it has no zone).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• convert_time read-only

  Given a UTC instant (or a wall time in a source location), return the corresponding local time in each of up to 50 target locations. Results include a source_url linking the matching worldclock.pro page when available.

  Parameters:

  • targets (required) — array
  • utc — string — The instant to convert, as an ISO 8601 string. Read as UTC if it has no zone designator.
  • from — object — Alternative to `utc`: a wall time in a specific source location.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• time_by_coordinates read-only

  Resolve the timezone for a latitude/longitude coordinate (via geo-tz) and return the local time there.

  Parameters:

  • latitude (required) — number — Latitude in degrees [-90, 90].
  • longitude (required) — number — Longitude in degrees [-180, 180].
  • at — string — Optional ISO 8601 instant to evaluate instead of now (read as UTC if it has no zone).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_dst_transitions read-only

  Report whether a location observes daylight saving time, the next clock change, and every summer/winter-time transition (date, local time, and before/after offset) within a year. The result includes a source_url linking the matching worldclock.pro page when available.

  Parameters:

  • location (required) — object — A location identified by exactly ONE of: query, timezone, or latitude+longitude together.
  • year — integer — Calendar year to list transitions for (default: the current year).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_cities read-only

  Find cities by name (multilingual, diacritic-insensitive) — useful to resolve a place to a canonical slug, IANA timezone, and coordinates before calling the time tools. Each result includes a source_url linking the city's worldclock.pro page.

  Parameters:

  • query (required) — string — City name or partial name (≥ 2 characters).
  • limit — integer — Max results (default 10).
  • country — string — Optional ISO 3166-1 alpha-2 country filter, e.g. "JP".

  Hints: read-only yes · destructive no · idempotent yes · open-world no
