Gets or sets the number of seconds that a KeyTime object represents.
The number of seconds that the KeyTime object represents.
This property is read/write. The default value is 0.
Setting this property is possible only through a type conversion syntax, when you set a property that takes a KeyTime as an attribute string. You cannot set the Seconds property as a distinct attribute of a KeyTime in XAML, because it is not possible to create a KeyTime element in XAML.
You can set or get the Seconds value in script by using object.property syntax, after you get an existing KeyTime as a property value. If you set the value on a running animation, the value will apply the next time the same animation is started.
If a property that takes a KeyTime is not explicitly set (either through scripting or XAML), the value of that property might be null. In this case, scripting for object.Seconds will produce an error because object is null.
The Seconds value is the converted summation of all the possible unit inputs for a KeyTime. For example, a KeyTime that is created with an attribute value of "0:01:00.555" will have a Seconds value of 60.555. Only the Seconds property exists for getting the representative value; there are no scripting properties for minutes, days, milliseconds, and so on.
