Subject: [ruby-core:53434] [CommonRuby - Feature #8096] introduce Time.current_timestamp


Issue #8096 has been updated by headius (Charles Nutter).


This is an *excellent* idea. Being able to get timestamps without creating an entire Time object would be really nice for code that does fine-grained timing.

Here's a benchmark of Time.now.to_i compared to the Java method System.nanoTime (the simplest way on JVM to get a timestamp).

https://gist.github.com/headius/5167793

Calculating -------------------------------------
       Time.new.to_i    106740 i/100ms
     System.nanoTime    187876 i/100ms
-------------------------------------------------
       Time.new.to_i  5457230.7 (��7.3%) i/s -   27111960 in   5.000000s
     System.nanoTime 17952011.5 (��9.2%) i/s -   88301720 in   4.976000s

Given that nanoTime likely makes the same native call this feature would, we could see a similar improvement if such a feature were standard.

May I suggest "Time.timestamp" instead? Do people really want timestamps that aren't "current"?

Feature #8096: introduce Time.current_timestamp

=begin
A lot of scenarios and applications require the use of Time.now.to_i which is used as current_timestamp in systems.

The introduction of Time.current_timestamp {or something with similar with different name} would provide implicit integer timestamp instead of going from 
Time.now -> time_object -> to_i -> integer timestamp value

So instead of 

(({> Time.now.to_i # Outputs => 1363274618}))

one could use

(({> Time.current_timestamp # Outputs => 1363274618}))
