unix
UNIX seconds timestamp. Constrained to the JavaScript `Date` safe range.
Adds `seconds`, `minutes`, `hours`, and `days` to an optional base timestamp. Input timestamp forms: - `unix=1711300000` - `unix_ms=1711300000000` - `iso=2026-04-16T09:00:00Z` - `iso=2026-04-16T09:00:00&source_tz=America/New_York` - `iso=2026-04-16T09:00:00&source_ip=8.8.8.8` - `iso=2026-04-16T09:00:00&source_lat=40.7128&source_lon=-74.0060` - `iso=2026-04-16T09:00:00&source_offset=-05:00` - if no input timestamp is provided, the base timestamp defaults to the request time Modifiers: - `seconds=30` - `minutes=15` - `hours=2` - `days=7` Target selector forms: - `tz=America/New_York` - `ip=8.8.8.8` - `lat=40.7128&lon=-74.0060` - `offset=-04:00` - `utc=true` Incompatible combinations: - at most one input timestamp form - at most one target selector family - use at most one of `source_tz`, `source_ip`, `source_lat`/`source_lon`, or `source_offset` - local-ISO companion selectors are valid only with `iso=...` that has no explicit offset - bulk is not supported on this route Examples: - `/v1/time/add?iso=2026-04-16T09:00:00&source_tz=America/New_York&days=1&tz=Europe/London` - `/v1/time/add?minutes=30&utc=true`
UNIX seconds timestamp. Constrained to the JavaScript `Date` safe range.
UNIX milliseconds timestamp. Constrained to the JavaScript `Date` safe range.
ISO-8601 timestamp. To supply a local wall-clock time without an explicit offset, pair it with one of `source_tz=Area/City`, `source_ip=...`, `source_lat=...&source_lon=...`, or `source_offset=±HH:MM`.
Used only with `iso=...` when the ISO value has no explicit offset.
Used only with `iso=...` when the ISO value has no explicit offset. Resolves that local wall-clock time through the timezone mapped from this IP address.
Used only with `iso=...` when the ISO value has no explicit offset. Provide together with `source_lon` to resolve that local wall-clock time through the timezone mapped from these coordinates.
Used only with `iso=...` when the ISO value has no explicit offset. Provide together with `source_lat`.
Used only with `iso=...` when the ISO value has no explicit offset. Interprets that local wall-clock time at this fixed UTC offset.

IANA timezone name. On bulk-capable routes, a comma-separated list enables bulk mode.
IP address. On bulk-capable routes, a comma-separated list enables bulk mode.
Latitude. Must be provided together with `lon`.
Longitude. Must be provided together with `lat`.
Fixed UTC offset in `+HH:MM` or `-HH:MM` format. On bulk-capable routes, a comma-separated list enables bulk mode.
Set to `true` to force UTC on routes that support it.
Custom date/time format template.
Set to `true` to ask the gateway to sign the final JSON response. Not supported on `/v1/time/clock`.
