Rfc 2822 defines the date: header. it declares the header a required part of an email message. the syntax for date headers is clearly laid out. still, even a perfectly planned world has storms. the truth is, many programs get it wrong. very wrong. or, they don't include a date: header at all. this often forces you to look elsewhere for the date, and hoping to find something.

for this reason, the tedious process of looking for a valid date has been encapsulated in this software. further, the process of creating rfc compliant date strings is also found in this software.
