this won't work if current time is 12:59 and so on.. because after addition it becomes 12:60 instead of 13:00

If you have ksh93 you can use the %T option to printf to manipulate the date
Code:
$ newtime=$(printf "%(%H:%M)T\n" "now + 1 minute")

Finally using the below for my query..........Thanks for all who ever replied and gave their valuable answers...

#!/bin/ksh
timehh=`date -u '+%H'`
timemm=`date -u '+%M'`
if test $timemm -eq 59
then
timehh=`expr $timehh + 1`
timemm=`expr $timemm - 1`
fi
curr_time="$timehh:$timemm"
timemm=`expr $timemm + 1`
new_time="$timehh:$timemm"
echo "$curr_time === $new_time"


Regards
