This is specifically designed for handling two # digit years. For example, if you wanted to treat all two digit # years prior to 70 as the year 2000+ you could write this: # # require 'time' # # Time.parse("01-10-31") {|year| year + (year < 70 ? 2000 : 1900)} # #=> 2001-10-31 00:00:00 -0500 # Time.parse("70-10-31") {|year| year + (year < 70 ? 2000 : 1900)} # #=> 1970-10-31 00:00:00 -0500 # # If the upper components of the given time are broken or missing, they are # supplied with those of +now+. For the lower components, the minimum # values (1 or 0) are assumed if broken or missing. For example: # # require 'time' # # # Suppose it is "Thu Nov 29 14:33:20 2001" now and # # your time zone is EST which is GMT-5. # now = Time.parse("Thu Nov 29 14:33:20 2001") # Time.parse("16:30", now) #=> 2001-11-29 16:30:00 -0500 # Time.parse("7/23", now) #=> 2001-07-23 00:00:00 -0500 # Time.parse("Aug 31", now) #=> 2001-08-31 00:00:00 -0500 # Time.parse("Aug 2000", now) #=> 2000-08-01 00:00:00 -0500 # # Since there are numerous conflicts among locally defined time zone # abbreviations all over the world, this method is not intended to # understand all of them. For example, the abbreviation "CST" is # used variously as: # # -06:00 in America/Chicago, # -05:00 in America/Havana, # +08:00 in Asia/Harbin, # +09:30 in Australia/Darwin, # +10:30 in Australia/Adelaide, # etc. # # Based on this fact, this method only understands the time zone # abbreviations described in RFC 822 and the system time zone, in the # order named. (i.e. a definition in RFC 822 overrides the system # time zone definition.) The system time zone is taken from # Time.local(year, 1, 1).zone and # Time.local(year, 7, 1).zone. # If the extracted time zone abbreviation does not match any of them, # it is ignored and the given time is regarded as a local time. # # ArgumentError is raised if Date._parse cannot extract information from # +date+ or if the Time class cannot represent specified date. # # This method can be used as a fail-safe for other parsing methods as: # # Time.rfc2822(date) rescue Time.parse(date) # Time.httpdate(date) rescue Time.parse(date) # Time.xmlschema(date) rescue Time.parse(date) # # A failure of Time.parse should be checked, though. # # You must require 'time' to use this method. # def self.parse: (String date, ?_TimeLike now) ?{ (Integer) -> Integer } -> Time # # Works similar to +parse+ except that instead of using a # heuristic to detect the format of the input string, you provide # a second argument that describes the format of the string. # # If a block is given, the year described in +date+ is converted by the # block.
