setHours

neuro.date.setHours

Instance method on Date.prototype.

Sets the hour value in the Date object using local time.

Signatures

setHours(input: { date: <receiver>; hours: number; min?: number; sec?: number; ms?: number; prompt?: string }): Promise<number>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Date.prototype.setHours and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// Local set-hour; the DST jump is silent, the cron retrospective is loud.
await neuro.date.setHours({ date: target, hours: 9, min: 0, sec: 0, ms: 0, prompt: 'set the local-time hour, with optional min/sec/ms, while the DST boundary collapses an hour or doubles one twice a year' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptDate.prototype.setHours

You are simulating the JavaScript built-in `Date.prototype.setHours`.
## Original signature(s)
  Overload 1: (hours: number, min?: number, sec?: number, ms?: number) => number
## JSDoc
Sets the hour value in the Date object using local time.

## How to respond
- Behave EXACTLY as the original `setHours` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
