Ruby Noob? create ruby ​​date

Question

I need to convert some ASCII binaries to MySQL. These files and records contain several 6-digit fields representing dates in the form 090403 (yymmdd), and I would like to convert them to 2009-04-03. How to create a date object with this input?

Answer 1

You need the ParseDate module:

require 'parsedate' # => true res = ParseDate.parsedate("090403") # => [9, 4, 3, nil, nil, nil, nil, nil] Time.local(*res) # => Fri Apr 03 00:00:00 +0100 2009 

Answer 2

Two solutions

(a) The date class has the strptime method

 d = Date.strptime("090403", "%d%m%y") 

This gives you the standard Date class.

(b) The standard library has a parsedate method

 require 'parsedate' pd = ParseDate.parsedate("090403") Time.local(pd) 

It gives you a time class.

Option (a) you probably want

Answer 3

You can use the DateTime.strptime method.

Answer 4

 > d = Date.strptime("090403", "%y%m%d") => #<Date: 4909849/2,0,2299161> > puts d 2009-04-03 

Answer 5

I prefer to use Time.

 require 'time' Time.parse("090403").strftime("%Y-%m-%d")
