You either need to send it via an AJAX postback, or set it in a cookie and read that out in the next page request, or do all the processing with it client side, or have the user set their home time zone in a profile and calculate it on the server side.

The easiest way is to set a cookie (with a fairly short i.e. 1 day expiry) on the home/login page and read that. (I think JavaScript can write cookies that are sent back to the server, anyway.)

Add

C#

runat='server'

attribute to the control whose value you are setting in the javascript code above.

I hope I was able to solve your problem
