Okay, this works for me when I feed it your last output on stdin:
Code:
#!/bin/bash

while read USER TERM WKDAY MON DAY TIME DASH END DURATION
do
        [ "$TERM" == "console" ] || continue
        [ "$DASH" == "-" ] || continue
        [ "${DURATION:0:1}" == "(" ] || continue

        # Remove brackets
        DURATION="${DURATION:1:$((${#DURATION}-2))}"
        # Strip +07 garbage
        DURATION="${DURATION//+[0-9][0-9]/}"

        # Split 05:30 into 05 and 30
        IFS=":" read HOUR MIN <<< "$DURATION"

        # Strip leading zeroes, otherwise BASH will assume the
        # numbers are octal!
        HOUR="${HOUR#0}"
        MIN="${MIN#0}"

        ((MIN+=(HOURS*60)))

        echo $USER $MIN
done | awk '{ t[$1]+=$2;        }
        END {   most=""
                for(key in t)
                        if(t[most] < t[key])    most=key;

                printf("%s\t%02d:%02d\n", most, t[most]/60, t[most]%60);
        }'

Code:
$ ./last.sh < lastdata
panman82        16:09
$

A pure awk solution might be more elegant but the necessary string operations seem much easier in the shell.
