Get user TimeZone without using JavaScript

I am not sure if this section is right one to post my problem. However, I have
heard something about the user's time being in the request object. I can't find
it. I have searched a lot...But all the solutions have used JavaScript. Is there
anyway around to get the user timezone without using JavaScript. 

Thanks in advance :)

I dont think there is a way to detect that ,

i think you may use the User  IP address to detect its timeZone,

but in general , the user will be asked to specify its time zone .

Thanks anas. These days Internet has many routes.it is difficult to get the
actual location. And also what about the proxy servers.? I want to use the
JavaScript but without using any cookie and post back to send the timezone to
the server.

Thanks for your reply
