The t:DUR attribute is a value relative to the value of the element's t:begin attribute. by contrast, the t:end attribute represents an absolute value along the parent element's timeline starting at 0 seconds. do not use the t:dur attribute on the same element as the t:end attribute.
a dur value of 0 is invalid. if 0 is specified, the default value is used instead.
