reagards,

Sure,

Code:
BEGIN{FS=","}NR==1{next}$2>m{h=$1;m=$2}END{print "BUSY HOUR = " h}' file

m is a variable for the max value
h is a variable for the hour

BEGIN{FS=","} = set fieldseperator

NR==1{next} = ignore 1st record

$2>m{h=$1;m=$2} = if 2nd field is greater than the last greatest value set m with the new value and set variable h with the hour

END{print "BUSY HOUR = " h} = print the the hour with the highest value of the 2nd field
