Hi guys,

I've configured for nginx to cache static like jpeg|png. The problem is if request with MISS status, it will show a non-zero value request_time, but if a HIT request, the request_time value is 0.000.
This is an nginx bug and is there anyway to resolve it.

My log format

```
log_format cache '$remote_addr - [$time_local] $upstream_cache_status $upstream_addr '
'"$request" $status $body_bytes_sent $request_time ["$upstream_response_time"] "$http_referer" '
'"$http_user_agent" "$host" "$server_port" "$connection"';
```

I read a topic about this but this is not informational. I've try to set timer_resolution to 0ms but nothing was changed

Thanks
