Envoy: Access log's timestamps are still in UTC regardless a containter's timezone?

[hawran]

Hi,
I'm trying to configure envoy (as a docker container) to use my format string and I've noticed a strange behaviour:

1. All timestamps use UTC.
Finally I've managed to persuade the image to use my timezone, hence envoy uses timestamps using my localtime.
However:

2. When I try to set up my access log's format (for a http connection manager), all timestamps are still in UTC.

What am I missing?

Regards,
hawran

PS: Is there any possibility to use whatever second fractions (mili / micro / nano ) for the %START_TIME% command operator as is described for the command line formatter parameter? (as mentioned here?)

Could this help?

UTC is by design. Trust me, you really want UTC.

For partial seconds see https://github.com/envoyproxy/envoy/pull/3269

OK, thank you.

I really don't want UTC
