How do I get elapsed time in milliseconds in Ruby?

Question

If I have a Time object got from :

Time.now

and later I instantiate another object with that same line, how can I see how many

Answer 1

Time.now.to_f can help you but it returns seconds.

In general, when working with benchmarks I:

• put in variable the current time;
• insert the block to test;
• put in a variable the current time, subtracting the preceding current-time value;

It's a very simple process, so I'm not sure you were really asking this...
