Hello Daniele,
About the DateTime in ironruby, you might encountered same problem
with me. The implementation in IronRuby use .NET DateTime struct which
unable to maintain reference id.
I was introduce RubyDateTime class to solve this problem, but
unfortunately i didn't have time to finish it yet.
My todo list:
RubyDateTime.cs
- Replace DateTime in the codebase
- Converter.IsIntegral might need to be
- override Equals, HashCode, and ToString (remember this is immutable
DateTime)
- Constructor as a DateTime
- Make it Serializable
- see msdn.com any other interfaces/attributes to propagate to
- define implicit operator converting from and to DateTime so that
Ruby code can pass a Ruby Time object to a CLR method that expects
DateTime.
- change comment "“Encapsulates DateTime and supports mutating of
instances (whereas DateTime is immutable)”
- Time#utc spec should be "modifies the receiver"
- fix for rfc2822 spec

Bests,

Hi,
I encountered a few bugs in IronRuby while running the specs for
rufus-scheduler (http://github.com/jmettraux/rufus-scheduler/). I'm
fixing some of them right now, but in the meanwhile I bumped into a
couple of issues running the rubyspecs for the Time class:
* Time.at creates a dup time object with the value given by time
See http://gist.github.com/169660 . The implementation of
DateTime.Create(object, DateTime) returns a new DateTime created from
self, but the two instances on the "ruby side" have the same
object_id. I investigated a little bit more and noticed that there is
only one DateTime element in the associated _valueTypeInstanceData of
the current RubyContext. Well, no wonder: DateTime is a ValueType, the
two values shares the same hashcode and _valueTypeInstanceData is a
Dictionary<object, RubyInstanceData>. Honestly I don't think this
poses any real problems, but still it is a different behaviour from
the MRI. Thoughts?
* Time.at converts to time object
There was a bug in Time#at which got already fixed on my local
repository, even so this spec is still failing. This time the problem
is related to the rubyspecs: if you take a look at the the localtime
method in rubyspec\core\time\fixtures\methods.rb (it returns the
current local time from the OS), you can note that it works only for
POSIX-systems. I can't think of a good and clean way to get this
fixed, hope to hear Jim's thoughts about this one.
Thanks,
Daniele
