This website is loaded with "time and time zones" with so much more information / links provided within...
From the Authors:
Time and Date AS is based just outside Stavanger, Norway, where our teams work together to operate timeanddate.com, the world's top-ranking website for time and time zones. With free online services you can rely on, we make it easier to organize your life, both at work and at home.
Our German and Norwegian sites, timeanddate.de and timeanddate.no, offer the same high level of accuracy and reliability as our English language site.
You can also enjoy our content on your phone or tablet because we make apps for iOS and Android too!
And if you are a developer, try our API service to tap into our extensive databases for time and time zones, calendars, holidays, and more.
