How to add an hour or a minute to a time?
Hi,

The timestamp is June 06 2011 11:05AM
i need 2 results.

first, an hour added to it, June 06 2011 12:05AM
second, a minute added to it, June 06 2011 11:06AM

How can i do this?

Also when it reaches 12:59, it needs to start from 1 again without giving the output as 13:00. it should be 1:00 again

Try a time calculator. There are some on the Web. Or use paper and a pencil.

I can suggest you need do it in a shell, but it's very hard to know what system you use. Please try to be more exact.

Use DateTime from CPAN - very easy. Or you can use localtime function (or standard Time::localtime module).

i have used like this. But this gives 13:00 instead of 1:00 while adding.

Code:
my $hr_to_add = 1 * 60 * 60;
my $hr_dt = qx/
  date -d "$dt_str" +%s
  / + $hr_to_add;
my $hr_var = strftime( '%B %d %Y %H:%M%p', localtime $hr_dt );



Can you please be more specific
