+ * FUNCTION: pkix_ExpirationChecker_Initialize
+ * DESCRIPTION:
+ *
+ *  Creates a new CertChainChecker and stores it at "pChecker", where it will
+ *  used by pkix_ExpirationChecker_Check to check that the certificate has not
+ *  expired with respect to the Date pointed to by "testDate." If "testDate"
+ *  is NULL, then the CertChainChecker will check that a certificate has not
+ *  expired with respect to the current date and time.
+ *
+ * PARAMETERS:
+ *  "testDate"
+ *      Address of Date representing the point in time at which the cert is to
+ *      be validated. If "testDate" is NULL, the current date and time is used.
+ *  "pChecker"
+ *      Address where object pointer will be stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a CertChainChecker Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.
