Description

The time on certificates returned by read_state requests is currently not checked in agent-js.

It is a good practice to check the time to avoid using stale data. For example, we do it for asset certification in the service worker because otherwise a malicious node could serve stale/outdated HTTP assets.

Fixes SDK-1132

How Has This Been Tested?

new unit tests with mocked time and custom errors
