How to change istio log time zone to 'Asia/Shanghai'?

Answer 1

This topic has already been discussed on envoy github as istio uses envoy access log.

As far as I know currently it's not possible. There are github issues I mentioned above about that which says that it's designed in UTC by default.

• Access log's timestamps are still in UTC regardless a containter's timezone
• How to change the log time zone of each component of Istio to CST format

It's not even possible to persuade the image to use your timezone as envoy will use the UTC anyway.
