All I can say is: it works for me.

"http" section of nginx.conf:

===
http {
    map $time_iso8601 $expiresc {
        default "3h";
        ~T22 "@00h00";
        ~T23 "@00h00";
    }

    server {
        listen       8080;
        location /a/ {
            expires     $expiresc;
        }
    }
}
===

Selected output from

$  curl -i http://127.0.0.1:8080/a/b

HTTP/1.1 200 OK
Server: nginx/1.9.2
Date: Mon, 01 Feb 2016 09:09:06 GMT
Expires: Mon, 01 Feb 2016 12:09:06 GMT
Cache-Control: max-age=10800


If you get different output, it may be worth investigating properly what
is happening.

But it may be simpler to just deploy your tested-working version.

Good luck with it,
