Time.parse

[Joel VanderWerf]

Time.parse is documented in ri, but doesn't seem to be defined. Do I
need to require something from the stdlib?

I'm looking for an easy way to convert things like "4:30" to relative
values--seconds since "00:00:00". I can just parse manually, of course,
but was hoping for a standard way to do it, like

Time.parse("4:30") - Time.parse("0:00")

Seems that it's an extension of the Time class by time.rb:

require 'time'
p Time.parse("4:30") - Time.parse("0:00")

#=> 16200.0

I've had trouble with something like this before... would it be
conceivable that RDoc could be made to add a note to each piece of ri
documentation saying what file it is defined in? I think this could be
especially useful when looking up methods that are added to the Kernel
or Object, or tacked in the Math module.

cheers,

Nice and easy. Thanks!

Next question:

irb(main):008:0> Time.parse("sljhfslf")
=> Wed Jun 16 17:31:44 PDT 2004

That's the same as Time.now. But ri Time.parse says:

ArgumentError is raised if ParseDate cannot extract information
from +date+ or Time class cannot represent specified date.

Is there any other way to validate a time?
