Code:
#! /bin/bash

IN_A='01:02:03'
IN_B='04:05:06'

VAL_A=$( echo $IN_A | sed 's/://g' )
VAL_B=$( echo $IN_B | sed 's/://g' )

if [ $VAL_A -gt $VAL_B ]
then
  echo "$VAL_A <gt> $VAL_B"
else
  echo "$VAL_B <gt> $VAL_A"
fi

exit 0

Code:
#!/bin/bash

var="00:00:10"
varbis="00:00:09"

if [ $var = "00:00:10" ] ;then
echo same
fi

if [ $varbis != "00:00:10" ] ;then
echo not the same
fi
exit

be careful to let spaces between each fields between the [ ].
Code:
[ $var = "00:00:10" ]

isn't the same as
Code:
[$var = "00:00:10"]
