HI
I need script which can find difference between two dates
Example:
TS1="Feb 25 20:36:55 IST 2009"
TS2="Feb 26 02:36:55 IST 2009"

I should get output as 06:00:00

TS1="Feb 25 20:36:55 IST 2009"
TS2="Feb 26 22:36:55 IST 2009"

Output should be 1Day:02:00:00

Please need help to resolve this

I had tried script but not working properly
#!/bin/bash
TS1="Feb 25 20:36:55 IST 2009"
TS2="Feb 26 02:36:55 IST 2009"
echo TS1 is $TS1 ;
echo TS2 is $TS2 ;
Y1=`echo $TS1 | awk -F " " '{ print $NF }'`
echo Year1 is $Y1 ;
Y2=`echo $TS2 | awk -F " " '{ print $NF }'`
echo Year is $Y2 ;
M1=`echo $TS1 | awk -F " " '{ print $1 }'`
echo "Month1 is $M1" ;
M2=`echo $TS2 | awk -F " " '{ print $1 }'`
echo "Month2 is $M2 ";
Day1=`echo $TS1 | awk -F " " '{ print $2 }'`
echo "Day1 is $Day1 ";
Day2=`echo $TS2 | awk -F " " '{ print $2 }'`
echo "Day2 is $Day2 ";
HR1=`echo $TS1 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $1 }' `
echo HR1 is $HR1
HR2=`echo $TS2 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $1 }' `
echo HR2 is $HR2
M1=`echo $TS1 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $2 }' `
echo Minute1 $M1
M2=`echo $TS2 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $2 }' `
echo Minute1 $M2
S1=`echo $TS1 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $3 }' `
echo Second1 is $S1
S2=`echo $TS2 | awk -F " " '{ print $3 }' | awk -F ":" '{ print $3 }' `
echo Second2 is $S2
if [ $S1 -lt $S2 ]
then
Second_Diff=`expr $S2 - $S1`
else
S2=`expr $S2 + 60`
M2=`expr $M2 - 1`
Second_Diff=`expr $S2 - $S1`
fi
echo Second_Diff is $Second_Diff
#### End of seconds
### Start for Minutes comparison###
if [ $M1 -lt $M2 ]
then
Minute_Diff=`expr $M2 - $M1`
else
M2=`expr $M2 + 60`
Minute_Diff=`expr $M2 - $M1`
HR2=`expr $HR2 - 1`
fi
echo Minute Diff $Minute_Diff
### End of Minutes
### Compare Hour comparision####
if [ $HR1 -lt $HR2 ]
then
Hour_Diff=`expr $HR2 - $HR1 + 24`
else
HR2=`expr $HR2Hr + 24`
Hour_Diff=`expr $HR2 - $HR1`
fi
echo "Second Diff is $Second_Diff"
echo "Minute Diff is $Minute_Diff"
echo "HR_Diff is $Hour_Diff";
printf "Total time taken for build is %2.2d:%2.2d:%2.2d\n" $Hour_Diff $Minute_Diff $Second_Diff

Appreciate your help to resolve this
Thanks
