Arrays in awk (and php) are purely associative. So you can say

Code:
ip[$1]++;

Getting the busiest date and hour pretty much requires perl, but it's possible to do in gawk and maybe nawk. You'll need the mktime function in the least. It's ugly and you need to populate the full months table and some additional parsing.

Code:
BEGIN { m["Jan"]="01"; m["Feb"]="02"; } # and so on for all months
{ 

# split time field into numbers and letters
split($4,lt,"[^0-9a-zA-Z-]*"); 
# construct timestamp into internal unix representation
ts=mktime( lt[4] " " m[lt[3]] " " lt[2]  " " lt[5]  " " lt[6]  " " lt[7]  " " lt[8]); 
# you don't care about minutes and seconds, so just replace lt[7] and lt[6] with 0's. You could make *two* timestamps -- one for just the days (hours 0'd out) and another for just the hours (always Jan-1-1970, but with the hour filled in).

# bump count for this ip address
ip[$1]++; 
# 
day[ts]++;
}

END { 
  # find busiest day
  frequency=-1; busiest=-1;
  for (d in day) {
   if (day[d] > frequency) {
      frequency=day[d];
      busiest=d;
   }
  }
  print "busiest day: " busiest " hit " frequency " times";
  
}

First, finish filling out the months table in the BEGIN block. Second, the time-zone doesn't correctly get registered. Replace lt[8] with $5. Third, feel free to insert "print" statements to get some debugging output. I saw only a few lines of the log file, and I tested my code only against those liens.
