.NET Rocks!

Date and Time with Matt Johnson

Episode #1230 Tuesday, December 15, 2015

It's only date and time, how hard could it be? Carl and Richard chat with Matt Johnson about the challenges of really managing dates, times and time zones properly. The world is a complicated place, and time zones are a relatively new invention that is as much driven by politics as geography. And then there's daylight saving time, which is even worse! Matt talks about the simple mistakes that developers can make assuming behavior around dates and time that can lead to significant failures in your application. He also digs into the tools to make your life easier, especially Noda Time, an open source library for doing dates, times, time zones and daylight saving time right. Time to check it out!
