Following are the attributes in the Assertions group. (The total valid duration of an assertion is defined by the values set in both attributes.)
This attribute specifies the number of seconds before a timeout occurs on an assertion. The default is 420.
This attribute is used to calculate the notBefore time of an assertion. For example, if the IssueInstant is 2002-09024T21:39:49Z, and the Assertion Skew Factor notBefore Time value is set to 300 seconds (180 is the default value), the notBefore attribute of the conditions element for the assertion would be 2002-09-24T21:34:49Z.
