Can't reset my gametime to zero in XNA

I'm creating a game with XNA 4.0 and I have a problem with resetting the game time in my game,

the problem is I'm using this code for adding my objects in game:

Timespan prevSpawn = timespan.zero;
Timespan objectSpawnTime = timespan.fromsec(5);

if (gameTime.TotalGameTime - prevSpawn> objectSpawnTime)
        {
            prevSpawn = gameTime.TotalGameTime;
            AddObject();
        }

I want to reset the game time to zero, when start the game again or game end and goes to mainmenu and hit the play again, I want to reset gametime.

For a more accurate timer, you would be better using a time span, and a DateTime vairable. Set the DateTime to now when you want to start the timer, and in the TimeSpan do something like this:

timer = StartTime - DateTime.Now;

This will give you a timer you can deploy at any time.

As i understand from the MSDN entry below, the GameTime.TotalGameTime property will continue 'ticking' until you end the game, or, entire application.

http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.gametime.totalgametime.aspx

Perhaps it would be wiser to use your own object, for which you can reset with any of your actions and hence have more control over the time span. Then you could still use this property for counting the difference from one and the other.

i.e. when you reset/restart etc, do not refer to TotalGameTime and try to make it be zero, but refer to your own object's timespan, or to (TotalGameTime - TimeWhenReset) where TimeWhenReset is the timespan copied from TotalGameTime when you reset.

This is untested, but I think that it should work if I understood correctly.
