... while it should properly raise a Ruby TypeError, such as with MRI:
ruby -rtime -e "Time.strptime(0, '%Y-%m-%d')"
time.rb:432:in `_strptime': no implicit conversion of Integer into String (TypeError)
ruby -rtime -e "Time.strptime(nil, '%Y-%m-%d')"
time.rb:432:in `_strptime': no implicit conversion of nil into String (TypeError)
