# Date.jisx0301 (from ruby core) --- Date.jisx0301(string='-4712-01-01'[, start=Date::ITALY], limit: 128) -> date --- Creates a new Date object by parsing from a string according to some typical JIS X 0301 formats. Date.jisx0301('H13.02.03') #=> #<Date: 2001-02-03 ...> For no-era year, legacy format, Heisei is assumed. Date.jisx0301('13.02.03') #=> #<Date: 2001-02-03 ...> Raise an ArgumentError when the string length is longer than *limit*. You can stop this check by passing `limit: nil`, but note that it may take a long time to parse. (from ruby core) --- d.jisx0301 -> string --- Returns a string in a JIS X 0301 format. Date.new(2001,2,3).jisx0301 #=> "H13.02.03"
