How to Increment or add minutes???;-)
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"


Regards

Try this:

Code:
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).

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"
