DateEqualsIfExists

DateEqualsIfExists

DateEqualsIfExists compares a datetime in a request to a list of datetimes in your policy. Datetime comparisons compare down to the second; so for DateEquals to match, the time must match exactly.

To match a request, the context key can be absent, but if present it must match at least one of the datetimes in your policy.

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