Hello.
You can use:
ini=`date +'%s'`; sleep 5; fin=`date +'%s'`
difference=`expr $fin - $ini`
echo $difference

# Calc the difference between 2 dates in seconds, minutes, hours or days
dateDiff () { # 1: [-s, -m, -h, -d] 2: Date1 3: Date2
case $1 in
-s ) SEC=1; shift ;;
-m ) SEC=60; shift ;;
-h ) SEC=3600; shift ;;
-d ) SEC=86400; shift ;;
* ) SEC=86400 ;;
esac
DTE1=$(date -u --date "$1" +%s) # Converts date into UNIX timestamp
DTE2=$(date -u --date "$2" +%s)
if [ $DTE1 -gt $DTE2 ]
then let "DIFFSEC=(DTE1-DTE2)/SEC"
else let "DIFFSEC=(DTE2-DTE1)/SEC"
fi
echo $DIFFSEC
}
echo $((($(date +%s) - $(date -r abc +%s))/3600))
