Spotfire Node Manager trust fails with error "Response is unreliable: its validity interval is out-of-date"

The Node Manager is either offline or the trust fails. The following error is returned in the <Node Manager>\nm\logs\nm.log file:

 ==================================================================
Response is unreliable: its validity interval is out-of-date; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Response is unreliable: its validity interval is out-of-date
================================================================== 

Cause: This is generally caused due to time differences between the Spotfire Server and the Node Manager Server.

Update the time on both the Spotfire Server and the Node Manager server to have the same time stamp. Please note that the UTC timestamp should be the same on both machines.
