The TutsPlus.com site continues their "Building Your Startup" series of tutorials with the latest in the series covering automatic timezone detection based on the user's local time.

For the alpha release of Meeting Planner, I provided people the opportunity to change their time zone in user settings. However, for anyone outside of the western United States, they may have been wondering why their calendar appointments were at the wrong times. You have to know to look for the settings page.

As I approach the beta, I realized I needed to fix this as soon as possible. So I began to reflect on how best to resolve this. In today's episode, I'm going to walk you through my approach to automatic time-zone detection and how I integrated it into the user experience.

The tutorial starts off with a look at the current state of timezone detection, linking to two options that do mostly the same thing. Eventually, however, he decided on the jsTimezoneDetect library as it fit best with the needs of the application. He covers some of the thoughts that went into designing the user experience and the code required to integrate the Javascript library with his Yii2-based application. He ends the tutorial with a few additional considerations worth keeping in mind including timezone representation in ical exports and virtual meetings.
