Perl add one minute to the given date
Hello Gurus,

We have a query where we need to add one minute ( also we need to add 12 hrs in another query) to given date.

we tried using some functionalities like 'perl -e @d= $run_dt + 600' . however we were not succeeded.

Basically issue is we get date in following format "May18 2011 9:50PM"

we need output as "May 18 2011 9:51PM" ( add one min)

if its additiona of 12 hrs. it should be something like "May 19 2011 9:50AM"

Thanking you in anticipation.

Code:
perldoc Date::Manip

Code:
perl -Mstrict -MDate::Manip -e 'my $date="May18 2011 9:50PM";my $newDate=DateCalc($date, "10 Minutes"); print "$newDate\n";'

Thanks Skrynesaver, Unfortunately perldoc Date::Manip is not a valid module / does not exist in the linux version i am using.

Red Hat Enterprise Linux Server release 5.4 (Tikanga)
2.6.18-164.11.1.el5
is the verion i am using.

Thanks

Then I guess it's FormatToEpoch=>Add delta=>EpochToFormat.
Code:
perldoc -f localtime

@components=localtime($epoch_time)

The DateTime module may resolve the FormatToEpoch issues.

Yes.. But here i am stuck on how to convert "May 18 2011 9:50PM" into epoch seconds and viceversa... My given date contains AM/PM and no seconds ... Could you help me out ?

You could install the Date::Manip and make your life easier
or you may try something like this:

Code:
perl '-MPOSIX qw(strftime)' -le'

  $dt = qx/date -d "$ARGV[0]" +%s/ + $ARGV[1] * 60 * 60;
  
  print strftime "%B %d %Y %H:%M%p", localtime $dt;
  
  ' 'May 18 2011 9:50AM' 24


Code:
zsh-4.3.11[sysadmin]% perl '-MPOSIX qw(strftime)' -le'

  $dt = qx/date -d "$ARGV[0]" +%s/ + $ARGV[1] * 60 * 60;

  print strftime "%B %d %Y %H:%M%p", localtime $dt;

  ' 'May 18 2011 9:50AM' 24
May 19 2011 09:50AM

P.S. The solution is not portable because it relies on the GNU date program.
