NAME
Mail::Message::Field::Date - message header field with uris

INHERITANCE
 Mail::Message::Field::Date
   is a Mail::Message::Field::Structured

SYNOPSIS
 my $f = Mail::Message::Field->new(Date => time);

DESCRIPTION
Dates are a little more tricky than it should be: the formatting permits a few constructs more than other RFCs use for timestamps. For instance, a small subset of timezone abbreviations are permitted.

The studied date field will reformat the content into a standard form.

DIAGNOSTICS

Warning: Field content is not numerical: $content
    The numeric value of a field is requested (for instance the "Lines" or "Content-Length" fields should be numerical), however the data contains weird characters.

Error: Field name too long (max $length), in '$name'
    It is not specified in the RFCs how long a field name can be, but at least it should be a few characters shorter than the line wrap.

Warning: Illegal character in charset '$charset'
    The field is created with an utf8 string which only contains data from the specified character set. However, that character set can never be a valid name because it contains characters which are not permitted.

Warning: Illegal character in field name $name
    A new field is being created which does contain characters not permitted by the RFCs. Using this field in messages may break other e-mail clients or transfer agents, and therefore mutulate or extinguish your message.

Warning: Illegal character in language '$lang'
    The field is created with data which is specified to be in a certain language, however, the name of the language cannot be valid: it contains characters which are not permitted by the RFCs.

Warning: Illegal encoding '$encoding', used 'q'
    The RFCs only permit base64 ("b " or "B ") or quoted-printable ("q" or "Q") encoding. Other than these four options are illegal.

Error: No attributes for date fields.
    It is not possible to add attributes to date fields: it is not permitted by the RFCs.

Error: Package $package does not implement $method.
    Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package.
