You can use the time module.
irb(main):005:0> require 'time'
=> true
irb(main):006:0> Time.parse("October 20th, 2008, 7:48 pm")
=> Mon Oct 20 19:48:00 -0400 2008
hey thanks .... 
its working now...
but when i tried.,
Time.methods
=> ["inspect", "private_class_method", "const_missing", "clone",
"method", "public_methods", "public_instance_methods",
"instance_variable_defined?", "method_defined?", "superclass", "equal?",
"freeze", "mktime", "included_modules", "const_get", "methods",
"respond_to?", "_load", "module_eval", "class_variables", "now", "dup",
"protected_instance_methods", "instance_variables",
"public_method_defined?", "__id__", "eql?", "object_id", "const_set",
"id", "at", "singleton_methods", "send", "class_eval", "taint", "utc",
"frozen?", "instance_variable_get", "include?",
"private_instance_methods", "__send__", "instance_of?",
"private_method_defined?", "to_a", "name", "autoload", "type", "new",
"<", "protected_methods", "instance_eval", "<=>", "display", "==", ">",
"===", "instance_method", "gm", "instance_variable_set", "kind_of?",

"ancestors", "to_s", "<=", "public_class_method", "allocate", "hash",
"class", "instance_methods", "tainted?", "=~", "private_methods",
"class_variable_defined?", "nil?", "local", "untaint", "times",
"constants", "is_a?", "autoload?"]
got only these & parse method is missing ...
but in my friends PC parse method is present..
how to do it,
without using require 'Time'??

Just to add my tuppence.... the same applies to Date.parse (amongst other Date/Time methods). Can anyone explain why this is the case and why some documented methods in Date and Time are only available by requiring the respective module when other methods are available by default?
As i've come across this in the past i'm interested to know if there is a reason for this. Is this the intended behaviour or is it technically a "bug"?

You can use the time module.irb(main):005:0> require 'time'
=> true
irb(main):006:0> Time.parse("October 20th, 2008, 7:48 pm")
=> Mon Oct 20 19:48:00 -0400 2008------------------------------------------------------------------------

The entire Date class is available only after requiring it. Date simply isn't
a core class. Why Time.parse isn't in core while Time itself is, however, I
do not know.
As a sidenote: there are no *modules* Time or Date.

The things you have to "require" are written in ruby and have the
corresponding time.rb and date.rb - the methods available before this
are the ones written in C and compiled together with ruby.

Hate to be picky, but:
irb(main):001:0> Time.is_a? Class
=> true
irb(main):002:0> Class.is_a? Module
=> true

I don't think it'd be useful to define the term module to mean "class or
module" because that'd make it cumbersome to differentiate between modules
and classes (e.g. if someone said "modules can be included into classes" that
wouldn't be true by that definition because classes can't be included into
classes).
At any rate when I said module above I used that definition of the term module
which does not included classes as a subset. And I do believe that so did the
posters I was responding to (if they didn't that was a misunderstanding on my
part).
