How to set date and time mask in Nginx logs?

Question

Nginx

Tell me how to set your own time and date format in the Nginx logs?
The nginx site has scant information and no examples, it just states that there are 2 formats time_local and time_iso8601.
I want something like: [18:34:02 07.06]

Answer 1

map $time_iso8601 $my_time {
    ~^\d+-(\d+)-(\d+)T(\d+:\d+:\d+)  "$3 $1.$2";
}

And in log_format already use $my_time instead of $time_iso8601.
