Question about the %tr logformat formatcode

  I am using squid 3.3.x. I am trying to build my own logformat. While doing so, I noticed something strange. The documentation for 3.3's log format directive shows:

        Time related format codes:

                ts Seconds since epoch
                tu subsecond time (milliseconds)
                […]
                tr Response time (milliseconds)
                dt Total time spent making DNS lookups (milliseconds)

  However, the default "squid" logformat is:

#logformat squid %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %[un %Sh/%<a %mt

  So, looking at this, %tu is made 3-characters long, zero filled, which makes sense as it's milliseconds, so between 0 and 999. However, %tr, which is also documented to be milliseconds, is formatted into a 6-character space. Is %tr actually in microseconds? In which case, what about %dt?

  Thanks.
