stdweb is used by time versions <0.3.0. They have removed it from their current version. However a lot of our dependencies are tied to time 0.1.44 (the versions we are using of kube, opcua-client, chrono, warp (via its headers dep), k8s-openapi (via its chrono dep)) or time 0.2.26.

[kate-goldenring]

This issue was created as a warning by cargo audit. Closing as time has removed it and stdweb is not a direct dependency we can switch.
