Rails - Jul 2013 - Normalize dates taht are entered in more then one way.

Hi all,

I''m looking for a function, gem, etc. that will help to unify dates as
they
come in different formats. If the date comes in 
(1/2/2012,2012-01-02,01-02-2012,20120102,01022012, etc.) it would be nice 
to have it come out 2012-01-02. I''ve searched for a few days and only
find
ways to convert this format to that format. I might be using the wrong 
search terms and this may have already been addressed, if so, I apologize. 
In my previous PERL app I wrote a long If Else type converter that would 
test the date and then convert it in a specific order but I''m sure
someone
has solved it better then I could.

Any help would be greatly appreciated!!!

Mark

Where are the dates coming from?

The standard Date class can do parsing for some basic formats:

Date.parse(''2000-11-22'')
Date.parse(''11-22-2000'')
Date.parse(''1-2-2000'')
Date.parse(''11/22/2000'')
Date.parse(''22/11/2000'')
Date.parse(''20001122'')

But you should probably expect input that will be ambiguous. I''m not
sure
how you want to resolve that, unless you give your users "region" 
preferences, so they can select the format they prefer to use. (You need to 
know what "1-2-2000" means: can you just decide if it''s MDY
or DMY?)
