Datetime Advanced for LM Studio

An advanced datetime utility plugin for LM Studio. It gives local models structured awareness of the current date and time, timezone information, UTC/local conversions, and timestamp interpretation.

This project is an advanced fork of the original datetime plugin for LM Studio.

What it does

Datetime Advanced helps models avoid guessing when working with dates, times, timestamps, downloaded files, logs, web results, and sidecar metadata.

It provides tools for:

Getting the current datetime in structured form
Returning both UTC and local time
Including the active IANA timezone
Interpreting ISO timestamps, Unix seconds, Unix milliseconds, and date strings
Comparing a timestamp against the current moment
Classifying a timestamp as past, present, or future
Producing a human-readable relative time such as 4 minutes ago

Tools

Current Datetime Advanced

Returns the current date and time as structured data.

Example output includes:

UTC datetime
Local datetime
Timezone
Date
Time
Weekday
Unix seconds
Unix milliseconds

Interpret Datetime Advanced

Interprets a timestamp or date string relative to the current moment.

It returns:

Parsed UTC time
Local time in the selected timezone
Current UTC/local time
Difference in milliseconds and seconds
Relation: past, present, or future
Human-readable relative time

This is useful before claiming that a timestamp is old, recent, or in the future.

Why this exists

Local models do not reliably know the current date and time. They may also misread UTC timestamps as local time, confuse relative dates, or incorrectly claim that a timestamp is in the future.

Datetime Advanced gives the model a reliable tool for time-sensitive reasoning instead of relying on model memory.

Usage

Enable the plugin in LM Studio and ask time-sensitive questions such as:

What time is it?
What is today's date?
What day of the week is it?
Is this timestamp in the past or future?
Convert this UTC timestamp to my local time.
How long ago was 2026-07-08T13:01:12.958Z?

The model can call the datetime tools and use the structured result in its answer.

Works great with the Advanced plugin series

Datetime Advanced is designed to work well with other Advanced plugins:

For example, downloaded image metadata may include timestamps such as downloadedAt. Datetime Advanced can help the model interpret those timestamps correctly in UTC and local time.

Installation

Install from LM Studio Hub:

yuanjumay/datetime-advanced

Then enable the plugin in LM Studio.

Requirements

LM Studio 0.3.x or later
A model with tool calling support
