Ruby on Rails

You can extend the class yourself:

DateTime.class_eval do
  define_method(:truncate_precision) { |amount|
    puts amount
  }
end
=> #<Proc:0x0000001fa649a0@(irb):8 (lambda)>
DateTime.now.truncate_precision(sec: 10)
{:sec=>10}
=> nil

Hello.

I thought of adding a method in ActiveSupport that would be able to truncate custom precision amounts from a `DateTime` object.

For example:

    DateTime.now.truncate_precision(sec: 10) # => a new DateTime object minus the specified precision

I've needed this in a feature of mine and thought it might be useful to others.

What do you think? If we find this useful, I'd prepare a PR soon.

Cheers!
