Hello,

The following snippet:

#!/usr/bin/ruby -w  
require ‘date’  
class MyDate \< Date  
def self.today  
super  
end  
end  
puts MyDate.today.class

## end

prints out ‘MyDate’ with ruby 1.8.4 and 1.8.5, but ‘Date’ with 1.8.6

Is this a bug in 1.8.6, or the correction of a long lived bug in  
versions before ?

Cheers,

Han H.

It looks like perhaps the date library has changed in 1.8.6

[http://svn.ruby-lang.org/repos/ruby/tags/v1\_8\_6/NEWS](http://svn.ruby-lang.org/repos/ruby/tags/v1_8_6/NEWS)

" \* date

- Updated based on date2 4.0.3. "

I’ve not investigated further.

Indeed.  
My question was whether this should be considered a bug: #today is  
kind of a specialized version of #new, so I would expect the  
implementation to be #new like, and return a MyDate.

That sounds to me like someone used Date.new instead of self.new in  
class method somewhere. 🙂

And yeah, I’d look at it as a bug too. As a workaround, you can  
probably do a manual conversion…
