I realize that Perl has strftime, which allows you to pass a formatting object. The functionality I'm wondering if I can find is more like the following (from PHP):

```
$string1 = "Jun 6, 2012";
$string2 = "June 06 2012";
if (strtotime($string1) == strtotime($string2)) {
  echo "BLAMMO!";
}
// will echo "BLAMMO!"

```

The reason for this is a business need in which user-provided dates need to be compared for validation and extended logic (does this date fall within another daterange also provided, etc). Now, I realize I can write an entire library devoted to doing this, and I realize there are any number of potential pitfalls with date-parsing and you should never trust user input, but here are some basic assumptions.

1. The input is actually output from any number of software packages that conform to their own internal specifications for date formatting. They all follow some standard, but those standards are not uniformly normalized between programs. That being said, I should always be comparing two dates from the same program, but I may never know what format they may follow.
2. I realize the standards of any given system are likely to be different, but the assumption here is that we're feeding ALL of our dates into the same thing, so we can trust a consistent implementation, hopefully something in CPAN or another easily updated module.
