// Legacy dates:
// Any unrecognized word before the first number is ignored.
// Parenthesized text is ignored.
// An unsigned number followed by ':' is a time value, and is
// added to the TimeComposer. A number followed by '::' adds a second

// followed by milliseconds.
// Any other number is a date component and is added to DayComposer.
// A month name (or really: any word having the same first three letters
// as a month name) is recorded as a named month in the Day composer.
// A word recognizable as a time-zone is recorded as such, as is
// '(+|-)(hhmm|hh:)'.
