I'm assuming Time.now.iso8601 should work? Do I have a muffed
installation maybe? Do I have a muffed brain? :-)  Any other ideas?

C:\TEMP>ruby -v
ruby 1.8.2 (2004-12-25) [i386-mswin32]

C:\TEMP>ri Time.iso8601
----------------------------------------------------------- Time#iso8601
     iso8601(fraction_digits=0)
------------------------------------------------------------------------
     Alias for #xmlschema


C:\TEMP>irb
irb(main):001:0> Time.now.iso8601
