Issue/Introduction
When running a Policy Server and a CA Access Gateway as IdP, when
these ones create an Assertion as SAMLResponse, the IssueInstant value
is not following the SAML protocol (1). The time is in local time and not
UTC time :
The SAMLRequest is sent to CA Access Gateway with Zulu time :
IssueInstant="2020-12-28T15:50:06Z"
and the CA Access Gateway (SPS) Federation Services return in local
time :
IssueInstant="2020-12-28T15:43:59.425+01:00"
The same behavior can be seen on the Web Agent Option Pack.
Here's the flow and details of the Assertions :

1.3.3 Time Values
All SAML time values have the type xs:dateTime, which is built in to
the W3C XML Schema Datatypes specification [Schema2], and MUST be
expressed in UTC form, with no time zone component. SAML system
entities SHOULD NOT rely on time resolution finer than
milliseconds. Implementations MUST NOT generate time instants that
specify leap seconds.
p.9
IssueInstant [Required]
The time instant of issue in UTC, as described in Section 1.3.3.
