HELP: WORKING WITH MASTER PAGE
                            
                         
                        
                     
                 
                
                    I put a timer in my Master Page.
I have three (3) labels, the three labels are for
You've been log in: [Hours]:[Minutes]:[Seconds]
I have different web pages, but whenever I click other page, the timer reset like: 
You've been log in: [00]:[00]:[00]
What I want is once the user log in, the timer start
00:00:01 
When I click other pages, I want the timer to just continue as it is and not to reset. :(
