Bug #5885: 32 bit ruby 1.8 cannot load times from SSL certificates past 2038

Since dates past 2038 don't fit in a 32 bit time_t, ruby 1.8's OpenSSL extension cannot load them:

  $ cat t.rb
  require 'openssl'

  cert = OpenSSL::X509::Certificate.new <<-CERT
  -----BEGIN CERTIFICATE-----

  $ ruby -v t.rb

  t.rb:16:in `utc': time out of range (ArgumentError)
          from t.rb:16:in `not_after'
          from t.rb:16

I've tracked this down to ossl_asn1time_to_time() in ext/openssl/ossl_asn1.c calling Time.utc:

  return rb_funcall2(rb_cTime, rb_intern("utc"), 6, argv);

The certificate is valid:

  $ openssl x509 -in t.rb -noout -text
  Certificate:

          74:02:34:fa:af:fc:75:9a:fe:4f

Note that ruby 1.9 on a 32 bit platform doesn't have this problem since Time always has a 64 bit range:

  $ ruby19 -v t.rb
  ruby 1.9.2p0 (2010-08-18 revision 29036) [i386-freebsd8]
