I'm not able to reproduce this with Syck.  Can you try with Psych
instead?  Like this:

  ruby -v -ryaml -e 'YAML::ENGINE.yamler =3D "psych"; t0 =3D Time.now; p t0=
; p YAML::load(YAML::dump(t0)) =3D=3D t0'

I suspect your error is due to fractional second support.  Observe the
output of Syck compared to Psych:

  ### Using Syck
  $ ruby -v -ryaml -e 't0 =3D Time.now; p t0; p YAML::dump(t0)'

  "--- 2010-10-30 07:05:46.535362 -07:00\n"

  ### Using Psych
  ruby -v -ryaml -e 'YAML::ENGINE.yamler =3D "psych"; t0 =3D Time.now; p t0=
; p YAML::dump(t0)'

  "--- 2010-10-30 07:06:48.118999000 -07:00\n...\n"
