masem didn't actually mean a rollover - I think he was just using it as an analogy He meant "we're coming up to a point where all the nines go to zeros and we put a one in front".

I'm not quite sure what he means by check your string comparisons, because I can't see a way that it could change the outcome of a string comparison unless you were doing something terribly foolish like

if (substr($this_dat,0,4) eq substr($that_date,0,4) {
[download]

In which case it would come up false when you clearly would have wanted it to be true.

It was an interesting snippet anyway, just like yakko's below.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
