Convert duration to hours:minutes:seconds (or similar) in Rails 3 or Ruby

Question

I have a feeling there is a simple/built-in way to do this but I can\'t find it.

I have a duration (in seconds) in an integer and I want to display it in a friendly form

Answer 1

Summing up:

assuming that total_seconds = 3600

Option 1:

distance_of_time_in_words(total_seconds) #=> "about 1 hour"

Option 2:

Time.at(total_seconds).utc.strftime("%H:%M:%S") #=> "01:00:00"

Option 3:

seconds = total_seconds % 60
minutes = (total_seconds / 60) % 60
hours = total_seconds / (60 * 60)

format("%02d:%02d:%02d", hours, minutes, seconds) #=> "01:00:00"

use Option1 if you want words, Option2 if you want H:M:S format, Option3 if you want H:M:S format and there can be more than 24 hours
