Subject: When was the parse method added to the Time class?

Hi there, I've been running a particular script for a few years now
and only just noticed that it crashes on one particular system. (I
don't use that system very often and have run that script on it very
rarely.)

The offending code/line in question uses the Time.parse method.

I opened a CMD prompt and tried the following:
----
irb(main):001:0> d = '03/13/09 14:52'
=> "03/13/09 14:52"
irb(main):002:0> Time.parse( d )
NoMethodError: undefined method `parse' for Time:Class
        from (irb):2
...
irb(main):010:0> Time.methods.include? 'parse'
=> false
----

This system has Ruby 184-20 installed.  I know that version 186-25 and
up have the Time.parse method and the script works fine.  However, I
want to know what version of Ruby first included that method so that I
can identify the minimum requirements to run the script.

Can anyone tell me how I might find out what version/release of Ruby
first included that method?

Please let me know.  Thanks.

Paul.
