DateLessThan

DateLessThan compares a datetime in a request to a datetime in your policy. Datetime comparisons compare down to the second; so any value one second before the date in your policy will match the DateLessThan condition.

To match a request, the context key must exist in the request and must match the datetime in your policy.

You can NOT use policy variables in the value of this operator.
