[Feature idea] Truncating timestamp precision

[powi]

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!

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

Of course I can. I wanted to know if this seems useful to other people using Rails so I can start to work on this feature.

This doesn't feel to me like the sort of feature that warrants inclusion
in ActiveSupport. There are a multitude of possible functions similar to
this. I don't think it makes sense for ActiveSupport. This might be
useful as an extension module, along with other similar functions,
provided by a separate gem, but I'd have to down vote this for inclusion
in ActiveSupport.
