Ruby Convert time duration to Percentages


I'd like show that encoding log convert to percentage
Last log has that Current time is 00:01:07
movie file's runtime is 01:19:01

Code

require 'date'
start_time = DateTime.parse("00:00:00").to_time.to_i
current_time = DateTime.parse("00:01:07").to_time.to_i
end_time = DateTime.parse("01:19:01").to_time.to_i

total_second = end_time - start_time
current_second = current_time - start_time
(current_second.to_f / total_second.to_f * 100).to_i

Result

irb(main):084:0> (current_second.to_f / total_second.to_f * 100).to_i

=> 1

Method

def percentage current, runtime
  start_time = DateTime.parse("00:00:00").to_time.to_i
  current_time = DateTime.parse(current).to_time.to_i
  end_time = DateTime.parse(runtime).to_time.to_i

  total_second = end_time - start_time
  current_second = current_time - start_time
  (current_second.to_f / total_second.to_f * 100).to_i
end

Result

irb(main):094:0> percentage "00:01:07", "00:11:07"

=> 10
