Without the explicit error messge to go on, I can only suggest that you need to cast ViewState("StartTime") to a DateTime before you use it.

What I understood from your question is, you have some date time value in view state and you want to subtract it from current time.

var timespan = DateTime.Now.Subtract((DateTime)ViewState["DateTime"])

You must need to check the ViewState for null or valid date time value. Else you will get exception.
