Some of those timings overlap. From the man page:

time_namelookup - the time, in seconds, it took from the start until the
name resolving was completed.

time_connect - the time, in seconds, it took from the start until the TCP
connect to the remote host (or proxy) was completed.

time_pretransfer - the time, in seconds, it took from the start until the
file transfer was just about to begin.

So, time_connect includes the time taken to do the name lookup, and
time_pretransfer includes time_connect.
