The durations in your screenshot (1m19s, 3m15s, etc) are the Time To Live (TTL) values of those records. They tell you how long the value of the fields (CNAME, A) is still valid.

The --time option is unrelated to the TTL; it's described in the man page:

Print how long the response took to arrive.

You can convince yourself that dog and dig produce the same results for TTL by running:

watch dog --seconds baidu.com

and

watch dig baidu.com
