Adding 1 second to TimeSpan not working

I have this code:

 private void TimePlayedTimer_Start()
 {
   timePlayedStr = "00:00:00";
   timePlayed = new DispatcherTimer();
   timePlayed.Tick += timePlayedTimer_Tick;
   timePlayed.Interval = new TimeSpan(0, 0, 0, 1);
   timePlayed.Start();
 }

 void timePlayedTimer_Tick(object sender, object e)
 {
   TimeSpan ts = TimeSpan.Parse(timePlayedStr);
   ts = ts.Add(TimeSpan.FromSeconds(1));
   timePlayedStr = ts.ToString();
 }

When I debug this line by line, TimeSpan ts would equal "00:00:00" but after line ts = ts.Add(TimeSpan.FromSeconds(1)); it would some how have properties TotalDays = 2.313232439423 , TotalHours = 0.000555555 , TotalMilliseconds = 2000 rather than adding a 1 to the TotalSeconds properties I get these property values returned.

Does anyone know what I am doing wrong?

PS: I am just trying to add a second to the TimeSpan after every tick

The value for TotalDays is actually 2.31481481481481E-05, i.e. 0.0000231481481481481.

The value that you get is exactly what's expected at the second tick, you didn't manage to debug the first tick, and you are just interpreting the values wrong.

The TotalDays, TotalHours and TotalMilliseconds properties show the total value in the TimeSpan translated to that specific measurement, they don't form a value together.

2 seconds is the same as 2000 milliseconds, and the same as 0.000555555 hours.

If you want to look at the components in the value, you should look at the Days, Hours, Minutes, Seconds and Milliseconds properties. There you will find that the Seconds property is 2 and all the others are zero.

I think you're misreading the TotalDays value. When I run similar code I get my TotalDays value of 1.15740740740741E-05. That likely makes sense, one second is probably roughly that fraction of a day.

The Total* properties represent the overall value of the TimeSpan, not the discrete value of each portion of the TimeSpan.

Days, Hours, and Minutes will all be 0, but the Total* properties will represent the entirety of the value, even if those parts are fractional.
