Different versions and different compilers can cause these expressions to evaluate differently. The behavior in these cases is specifically undefined. It came up last year on PM. It has come up before on p5p as well.

[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
[stevieb]: I do date and time transformations in both Perl and Python, but not frequently enough to not have to search for the format params etc ;)
