[Ray Dashboard] Timestamps of logs on Dashboard are wrong

[RuiLi-5413]

What happened + What you expected to happen

I deployed a Ray Cluster with using Ray Kubernetes Operator on AKS and found the timestamps of logs on Ray Dashboard were different from my time zone. e.g. “2022-06-07 12:53:49,756” my time is “2022-06-07 21:53:49”.

I also tried on local K8s, the issue was same.

cc @alanwguo, should be solvable by examining log format logic.

We also have this problem two years later. Running date on the head node in our Ray Cluster on EKS gives "Mon Feb 19 02:58:13 PST 2024" even though server is in eu-west-1. Shouldn't it be UTC?
