In 7 years web programming career, I never met this problem before. In a recent project we needed to show browsers local time on the page. Few folks have solutions to do this server side but none of them work reliably. Why?
- Browsers don't send any timezone information
- You can send offset in headers / parameters but its only reliable for dynamic requests
- Convert all the server side timestamps to UTC. This makes server side code life way easier!
- I used very good jQuery library (Localtime) to convert iso8601 formatted dates to format required by application.
