[net.mail.headers] Date format survey.

ron@BRL-TGR.ARPA (Ron Natalie) (06/07/84)

Well, I thought I had a program for parsing RFC822 dates that worked
pretty well incorporating some of the common illegal formats that are
being used such as out of order days of week (I through it away), years
greater than 100, spelled out month names, misplaced commas, etc...
but I ran it on my current mail and the following hosts got caught:

	sun!l5@ucb-vax
	RUTGERS,
	PURDUE,
	USC-ECLB,
	DEC-MARLBORO,
	BNL

The errors in these cases were either the lack of separation between
the hours and minutes of the time (the colons are obligatory) or using
hyphens to separate the day of month and year from the month name.
