problem
Using any variation of
Time.now
is not a reliable way of measuring elapsed time. It may be affected by jumps in the local clock.solution
Instead, we can use a more reliable
Process.clock_gettime(Process:: CLOCK_MONOTONIC)
.For a detailed explanation, please read this blog post: https://blog.dnsimple.com/2018/03/elapsed-time-with-ruby-the-right-way/
