tempoch-js

Why it exists

tempoch-js brings the same time model used in Rust to JavaScript. The Node and browser packages stay aligned, so Julian dates, UTC, and periods behave the same in both places.

Key Features

• Node package: @siderust/tempoch
• Browser/WASM package: @siderust/tempoch-web
• JulianDate, ModifiedJulianDate, and Period APIs
• Interop with qtty-js quantity objects
• TypeScript declarations for both targets

Getting Started

npm install @siderust/tempoch @siderust/qtty

const { JulianDate } = require('@siderust/tempoch');
const { Hours } = require('@siderust/qtty/units');

const jd = JulianDate.j2000();
const later = jd.add(Hours(6));
console.log(later.toDate().toISOString());
