There may be only one date format in the specs, but reality is a lot
different.

When our header munger encounters a header that it can't parse, it can
send me a message including a copy of the pesky header. Occasionally
it's a bug in the parser. Normally it's a mail generating program that
doesn't play by the rules. Crazy dates are quite common, and this is
after our parser has been patched to know about the common illegal
formats.

I'll collect some samples if you want any data. (I'll even unpatch the
parser if you want a lot of data.)

And if you think there is a standard for dates.... I'm still amazed at
the number of messages that come through with "at" where there should be
an "@".
