Many Squid developers look at raw access logs. I suspect early Squid
developers wanted to first (or "left") access.log fields at a semi-fixed
position. Making most response time entries 6 characters long helps with
that goal.

Yes, %6tr is padded with spaces on the left (if its value is smaller
than 1000000) to make the entire value at least 6 characters long. This
is semi-documented in logformat directive description (look for
"width"): http://www.squid-cache.org/Doc/config/logformat/
