Hey runrig, thanks for the reply!

Cool, good info there, thanks!

I don't know if its the "best" way to go, but I was using the dates I created using the "Time::Piece" Module, then
I use the "Date::Manip" module to calculate a future date/time (*or past date if you needed to). The cool thing about
the Date::manip Module is that you can use human relate-able strings to calculate the date.

For example, before I added the "Date::Manip" Module, and currently still, I have a Command Line Option that the user inputs when
executing. Where the value of the argument is in the form of "a number followed by a time-unit". So for instance the
user could enter any of the following:
        --end-in="1hour"
        --end-in="2 hours"
        --end-in="3 hrs"
        --end-in="20 min"
        --end-in="30minutes"
        --end-in="1day"
        etc...............

Then after the user executes and after some error checking of the users input, I take the option the user entered, like "30 mins"
and then use that in the DateCalc Function, which is part of the Date::Manip Module. For the error checking I split the users
input into a number and a "time_unit", so "30mins" would get split into "30" and "mins", then I check each one.

So I would then take the current_date calculated by "Time::Piece qw(localtime)" and use that as the first argument to the "DateCalc"
Function, like so:

## Create the 'date manipulation' string for the DateCalc Function: # *The user's input is called $end_timeSpan... my $date_manip = "in $end_timeSpan" # For this example lets say: # $current_time == "07/17/2013 10:30:00" ### Calculate the future date from the $current_date: # *Output from function is in the form: # "2013071811:00:00" --> YYYYMMDDHH:MM:SS my $future_date = DateCalc($current_date,$date_manip) # After running the above & capturing each piece from DateCalc, the # $future_date == "07/17/2013 11:00:00", which would be 30 mins # from the $current_date.

So that's basically what I'm doing with the Date stuff. There is some other stuff I do with the Date and Time but that above is
the most important part.

Thanks again for all the suggestions and info.


Thanks Again,
Matt
