How to calculate difference between 2 TimeSpan ?

Question

Hello Everyone,

In my MVC4 project, I want to calculate the difference of employee's checkIn and checkOut time. But the 'workedTime' shows munus sign. How can I remove when page showing in browser?

 

TimeSpan d1 = new TimeSpan(00,00,00);

 

d1 ="08:14:55";

 

TimeSpan day = new TimeSpan(08, 30, 00);

 

TimeSpan workedTime = new TimeSpan(00, 00, 00);

 

workedTime = d1.Subtract(day);
