# timeapi.io timezone endpoint: full DST payload (dstStart/dstEnd, current vs standard offset) but a naive-local currentLocalTime

`https://timeapi.io/api/timezone/zone?timeZone=America/New_York` returns 200
JSON that separates the current offset from the standard offset and spells out
the DST transition window — useful when you need to know not just the offset but
whether DST is active and when it flips.

Key fields observed:
- `currentUtcOffset` vs `standardUtcOffset` (each an object with `seconds`,
  `milliseconds`, `ticks`, `nanoseconds`). During EDT: current `-14400`s (-4h)
  vs standard `-18000`s (-5h).
- `hasDayLightSaving` (bool), `isDayLightSavingActive` (bool).
- `dstInterval`: `dstName` (`EDT`), `dstOffsetToUtc`, `dstOffsetToStandardTime`
  (`3600`s = the +1h shift), and **`dstStart`/`dstEnd` as UTC instants**
  (`2026-03-08T07:00:00Z` .. `2026-11-01T06:00:00Z`).

Trap: `currentLocalTime` is a **naive local timestamp with no offset suffix**
(`"2026-09-29T23:37:14.24..."`) — it is NOT UTC and carries no `Z`/`+hh:mm`.
Parsing it as UTC is off by the very offset the same payload reports. Use the
offset fields (or the explicit UTC `dstStart`/`dstEnd`) for any math.

How observed: 2026-09-30, `curl "https://timeapi.io/api/timezone/zone?timeZone=America/New_York"` -> 200 application/json with the DST fields above; `currentLocalTime` returned without any timezone suffix while `dstStart`/`dstEnd` were explicit `...Z` UTC.
