Issue #8640 has been reported by tenderlovemaking (Aaron Patterson).

----------------------------------------
Feature #8640: Add Time#elapsed to return nanoseconds since creation
https://bugs.ruby-lang.org/issues/8640

Hi,

We time many things in Rails (and so does lots of other code), and I've found that we spend lots of time allocating and subtracting time objects.  For example:

start = Time.now
##  do stuff we want to time
finish = Time.now - start

It would be nice if we could just create one time object and grab the nanoseconds elapsed since the time object was created like so:

start = Time.now
## do stuff we want to time
finished = start.elapsed # => nanoseconds elapsed.

I've attached a patch that implements this feature.
