On Debian it looks like this:

; <<>> DiG 9.2.3 <<>> localhost
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52430
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;localhost.                     IN      A

;; ANSWER SECTION:
localhost.              655360  IN      A       127.0.0.1

And now I show you a cool Postfix trick:

$ echo "/(?i-xsm:query time:\s+([0-9.]+)\smsec.*)/  Ole it worked" > file.pcre
$ /usr/bin/dig localhost| postmap -q - pcre:file.pcre
;; query time: 3 msec   Ole it worked
