I need some help in converting this date time format to the one  
time.parse will accept.

irb(main):039:0\> time=“31/12/2007 5:00:00 PM”  
=\> “31/12/2007 5:00:00 PM”  
irb(main):040:0\> Time.parse(time)  
ArgumentError: argument out of range  
from e:/ruby/lib/ruby/1.8/time.rb:184:in `local' from e:/ruby/lib/ruby/1.8/time.rb:184:in`make\_time’  
from e:/ruby/lib/ruby/1.8/time.rb:243:in `parse’
