Converting times to formatted strings, dates, and datetimes.

### Methods

formatted_offset to_date to_datetime to_formatted_s to_time

### Constants

DATE_FORMATS | = | { :db => "%Y-%m-%d %H:%M:%S", :number => "%Y%m%d%H%M%S", :time => "%H:%M", :short => "%d %b %H:%M", :long => "%B %d, %Y %H:%M", :long_ordinal => lambda { |time| time.strftime("%B #{time.day.ordinalize}, %Y %H:%M") }, :rfc822 => "%a, %d %b %Y %H:%M:%S %z"

### Public Instance methods

formatted_offset(colon = true, alternate_utc_string = nil)

Returns the UTC offset as an +HH:MM formatted string.

      Time.local(2000).formatted_offset         # => "-06:00"
      Time.local(2000).formatted_offset(false)  # => "-0600"

to_date()

Converts a Time object to a Date, dropping hour, minute, and second precision.

      my_time = Time.now  # => Mon Nov 12 22:59:51 -0500 2007
      my_time.to_date     # => Mon, 12 Nov 2007

      your_time = Time.parse("1/13/2009 1:13:03 P.M.")  # => Tue Jan 13 13:13:03 -0500 2009
      your_time.to_date                                 # => Tue, 13 Jan 2009

to_datetime()

Converts a Time instance to a Ruby DateTime instance, preserving UTC offset.

      my_time = Time.now    # => Mon Nov 12 23:04:21 -0500 2007
      my_time.to_datetime   # => Mon, 12 Nov 2007 23:04:21 -0500

      your_time = Time.parse("1/13/2009 1:13:03 P.M.")  # => Tue Jan 13 13:13:03 -0500 2009
      your_time.to_datetime                             # => Tue, 13 Jan 2009 13:13:03 -0500

to_formatted_s(format = :default)

Converts to a formatted string. See DATE_FORMATS for builtin formats.

This method is aliased to `to_s`.

      time = Time.now                     # => Thu Jan 18 06:10:17 CST 2007

      time.to_formatted_s(:time)          # => "06:10:17"
      time.to_s(:time)                    # => "06:10:17"

      time.to_formatted_s(:db)            # => "2007-01-18 06:10:17"
      time.to_formatted_s(:number)        # => "20070118061017"
      time.to_formatted_s(:short)         # => "18 Jan 06:10"
      time.to_formatted_s(:long)          # => "January 18, 2007 06:10"
      time.to_formatted_s(:long_ordinal)  # => "January 18th, 2007 06:10"
      time.to_formatted_s(:rfc822)        # => "Thu, 18 Jan 2007 06:10:17 -0600"

## Adding your own time formats to `to_formatted_s`

You can add your own formats 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 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}") }

to_time()

A method to keep Time, Date and DateTime instances interchangeable on conversions. In this case, it simply returns `self`.
