[isTokenExpired()](./ibm-cloud-sdk-core.vpcinstancetokenmanager.istokenexpired.md)

`protected`


</td><td>

Returns true iff the currently-cached IAM access token is expired. We'll consider an access token as expired when we reach its IAM server-reported expiration time minus our expiration window (10 secs). We do this to avoid using an access token that might expire in the middle of a long-running transaction within an IBM Cloud service.
