Disagree, for numerous reasons. At sites where accesses are measured in 
hundreds or thousands per minute, logging the seconds becomes a lot more 
important. Also, a "session" can easily last less than a minute. Rounding 
session lengths up to even minutes would be worthless for short sessions.

That shouldn't be a problem in this day and age when even desktop PCs can 
synch up to SNTP servers. Sys Admins should be synching their servers as 
a matter of course.

Agreed on logging both begin and end of request.
