Instance Method Detail
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.
