Possibly you are thining of Date.new(), which allow negative months, and
negative daysofmonths, like the C mktime()? However, it doesn't allow
out of range values:

[ensemble] ~/p/ruby/vcard $ ruby -rdate -e "p Date.new(2004, 2, 29).to_s"
"2004-02-29"
[ensemble] ~/p/ruby/vcard $ ruby -rdate -e "p Date.new(2004, 2, 30).to_s"
/usr/lib/ruby/1.6/date.rb:147:in `new3': invalid date (ArgumentError)
        from -e:1
