Can you save a character by using && instead of and?

[stevieb]: ask a question on SoPW, and include at least a half-dozen examples of the input, and at least one example of expected output
[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 ;)
