Converting datetimes to formatted strings, dates, and times.
Returns the utc_offset as an +HH:MM formatted string. Examples:
datetime = DateTime.civil(2000, 1, 1, 0, 0, 0, Rational(-6, 24)) datetime.formatted_offset # => "-06:00" datetime.formatted_offset(false) # => "-0600"
Overrides the default inspect method with a human readable one, e.g., "Mon, 21 Feb 2005 14:30:00 +0000"
Convert to a formatted string. See Time::DATE_FORMATS for predefined formats.
This method is aliased to to_s.
datetime = DateTime.civil(2007, 12, 4, 0, 0, 0, 0) # => Tue, 04 Dec 2007 00:00:00 +0000 datetime.to_formatted_s(:db) # => "2007-12-04 00:00:00" datetime.to_s(:db) # => "2007-12-04 00:00:00" datetime.to_s(:number) # => "20071204000000" datetime.to_formatted_s(:short) # => "04 Dec 00:00" datetime.to_formatted_s(:long) # => "December 04, 2007 00:00" datetime.to_formatted_s(:long_ordinal) # => "December 4th, 2007 00:00" datetime.to_formatted_s(:rfc822) # => "Tue, 04 Dec 2007 00:00:00 +0000"
DateTime formats are shared with Time. You can add your own to the Time::DATE_FORMATS hash. Use the format name as the hash key and either a strftime string or Proc instance that takes a time or datetime argument as the value.
# config/initializers/time_formats.rb Time::DATE_FORMATS[:month_and_year] = "%B %Y" Time::DATE_FORMATS[:short_ordinal] = lambda { |time| time.strftime("%B #{time.day.ordinalize}") }
