This library extends the Time class:
conversion between date string and time object.
date-time defined by RFC 2822
HTTP-date defined by RFC 2616
dateTime defined by XML Schema Part 2: Datatypes (ISO 8601)
various formats handled by Date._parse (string to time only)
This library provides methods dedicated to special purposes:
RFC 2822, RFC 2616 and XML Schema.
They makes usual life easier.
This library doesn’t use
strftime. Especially rfc2822 doesn’t
%a and %b are locale sensitive
Since they are locale sensitive, they may be replaced to invalid weekday/month name in some locales. Since ruby-1.6 doesn’t invoke setlocale by default, the problem doesn’t arise until some external library invokes setlocale. Ruby/GTK is the example of such library.
%z is not portable
%z is required to generate zone in date-time of RFC 2822 but it is not portable.
