Hi all,

I want to add a minute to present time.
E.g:
if present time is 09:55, I want to make it 09:56.

Please help!!

I tried below script

#!/bin/ksh

timeut=`date -u '+%R'`
let timeut1=$timeut + 1
echo "timeut1 = $timeut1"

Try this:

perl -e '@d=localtime time() + 600; printf "%02d:%02d%s\n",$d[2]%12,$d[1],("AM","PM")[$d[2]/12]'

It adds 10 minutes to the current time.

try TZ..
first check this echo "$TZ"
it shows something like this
IST - 5:30 i guess
then TZ=IST - 5:31(not sure try + or -)
then type date you may get one min forward time
then change back the TZ to normal..

Thanks for reply...
but
MY SERVER TIME ZONE IS MST.
SO echo "$TZ" shows me MST7 as output.
so this will not help!!

Here I am converting MST time into GMT by date -u '+%R' (eg:15:44).
further I dont know how to increment(eg. 15:44 to 15:45).

are you using HP-UX??
then gothrough tztab man page once.. it may help..

timehh=`date -u '+%H'`
timemm=`date -u '+%M'`
curr_time="$timehh:$timemm"
timemm=`expr $timemm + 1`
new_time="$timehh:$timemm"
echo "$curr_time === $new_time"

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

Thanks a lot palsevlohit_123 !!!!

It helped me a lot..

10

it really helped you?? did you tried when min is 59??

11

Yes,...It really helped me.
i used a condition for that.(when min=59)incrementing hour...etc..

If you have ksh93 you can use the %T option to printf to manipulate the date

$ newtime=$(printf "%(%H:%M)T\n" "now + 1 minute")

Any other solution ...?

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"

$ date
Tue Aug 19 08:42:03 CDT 2008
$ TZ=CDT+4:59 date
Tue Aug 19 08:43:09 CDT 2008
