# IANA Timezone UTC Offset Lookup (DST-Aware)

> IANA Timezone UTC Offset Lookup (DST-Aware) is a paid API for AI agents from api.agishub.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns the exact UTC offset for a given IANA timezone at a specified instant, correctly handling DST transitions and fractional offsets like +05:30 and +05:45.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability iana-timezone-utc-offset-lookup-dst-aware-f6d1bc47 -d '<json body>'
```

Example prompt: What is the exact UTC offset for the Asia/Kolkata timezone right now — I need to know if it's really +05:30 including any DST adjustments.

## When to prefer this

Choose this endpoint when you need the precise UTC offset for a timezone at a specific historical, current, or future instant — especially when DST transitions matter or when dealing with fractional-hour offsets like India (+05:30) or Nepal (+05:45). Prefer this over a general 'current time' endpoint when you only need the offset, not the full local time, and when working with datetime arithmetic or timestamp normalization.

## Known failure modes

- Invalid or unrecognized IANA timezone name returns an error
- Malformed ISO 8601 datetime string causes a parsing error
- Timezone string is a common abbreviation (e.g. EST) rather than a valid IANA name and may be rejected or misinterpreted
- Missing required timezone parameter returns a validation error

## How this service works

Get the exact UTC offset of an IANA timezone at a given instant, DST-aware. Correctly handles fractional offsets such as India +05:30 and Nepal +05:45.

## Output

A JSON object containing the exact UTC offset for the specified IANA timezone at the given instant, including the offset in hours and minutes (e.g. +05:30, +05:45, -04:00), correctly reflecting DST state at that moment.
