JSTZ - Timezone Detection

JSTZ is a JavaScript library designed for client-side timezone detection within a user's browser, returning an IANA zone info key (e.g., 'America/Los_Angeles'). It is currently at version 2.1.1. As an unofficial fork of the original `pellepim/jstimezonedetect` project, its primary differentiator is enabling installation and usage via NPM for module-based environments (like Webpack or Browserify), as the original focused on CDN distribution. While there isn't a strict, frequent release cadence, updates have addressed specific bugs and improved TypeScript definitions. It's often used in conjunction with server-side frameworks or other date-time parsing libraries like Moment Timezone to determine the user's local timezone without requiring user input.
