Crappy code to read a pcap file with tcptrace and convert elapsed time into seconds

tcptrace-time-to-secs

TIMEZ=$(tcptrace -l $PCAP 2>/dev/null | awk 'NR==15 {print $3}') # Got a time value like 00:00:

OIFS="$IFS"
IFS=':'
read -a tokenized <<< "${TIMEZ}"
IFS="$OIFS"			
HOUR=( "${tokenized[0]}" ) 
MIN=( "${tokenized[1]}" ) 
SEC=( "${tokenized[2]}" ) #To reassign a variable assigned 
RES=$(echo "scale = 6; 3600*$HOUR+60*$MIN+$SEC" | bc)

echo $RES
