hello
The easiest way would be to use simple client-side JavaScript, as in:
var today = new Date ( );
and display that accordingly
But if you want or need to display the client local time in the desired culture-specific formatting, that takes a bit more work.
Currently there is no property or method in any class or namespace that can directly return this value, but you can use a combination of UtcNow and certain properties and methods of the TimeZone class along with a simple javascript function
maybe a working demo can help
