# Time Zone Date/Time Converter with DST Awareness

> Time Zone Date/Time Converter with DST Awareness is a paid API for AI agents from timezone-time.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Converts a local date and time from one IANA time zone to another, detecting and flagging DST edge cases where the time is invalid or ambiguous.

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 time-zone-date-time-converter-with-dst-awareness-1088c2c1
```

Example prompt: What time is 9:00am on March 12, 2025 in America/New_York when converted to Asia/Tokyo? Flag it if the time is invalid or repeated due to a DST transition.

## When to prefer this

Choose this endpoint when you need accurate, DST-aware time zone conversion with explicit validation of edge-case times (gaps and overlaps during clock changes). It is superior to simple offset-arithmetic approaches because it uses IANA time zone rules and actively flags times that are invalid or ambiguous — critical for scheduling, logging, or any application where DST correctness matters.

## Known failure modes

- Invalid IANA time zone string returns an error or degraded response
- Datetime not in YYYY-MM-DDTHH:MM format causes a parse error
- Time falling in a DST gap (non-existent) returns a flagged verdict with explanation
- Time falling in a DST overlap (ambiguous) returns a flagged verdict indicating it occurs twice
- Missing required query parameters (datetime, from_tz, to_tz) result in a validation error

## How this service works

Convert a date and time from one IANA time zone to another, flagging times that do not exist or occur twice at DST changes.

## Output

Returns the converted local time in the target zone, along with UTC datetime, UTC offsets and abbreviations for both source and target zones, a verdict on whether the input time is valid/ambiguous/non-existent due to DST, a human-readable summary, an array of reason strings explaining any anomalies, and optional degraded/disclaimer fields for edge cases.
