Time.parse does not throw ArgumentError on all invalid arguments
When Time.parse is not able to parse certain strings into valid Time objects, it does not throw ArgumentErrors. Instead, it returns Time.now.
For example, Time.parse("asdf") returns Wed Jul 16 17:03:19 -0400 2008.
This is observed on Mac OS X 10.5.3 running on a power pc and on Ubuntu 8.04 running ruby 1.8.6.
