Convert duration to hours:minutes:seconds (or similar) in Rails 3 or Ruby
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"
Note: it overflows, eg. for total_seconds = 25.hours.to_i
it'll return "01:00:00"
also
Option 3:
seconds = total_seconds % 60minutes = (total_seconds / 60) % 60hours = total_seconds / (60 * 60)format("%02d:%02d:%02d", hours, minutes, seconds) #=> "01:00:00"
Option 4:
ActiveSupport::Duration.build(total_seconds).inspect #=> "1 hour"# ORparts = ActiveSupport::Duration.build(total_seconds).parts"%02d:%02d:%02d" % [parts.fetch(:hours, 0), parts.fetch(:minutes, 0), parts.fetch(:seconds, 0)] #=> "01:00:00"
See: http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html
distance_of_time_in_words(3600) => "about 1 hour"
Ruby's string %
operator is too unappreciated and oft forgotten.
"%02d:%02d:%02d:%02d" % [t/86400, t/3600%24, t/60%60, t%60]
Given t is a duration in seconds, this emits a zero-padded colon-separated string including days. Example:
t = 123456"%02d:%02d:%02d:%02d" % [t/86400, t/3600%24, t/60%60, t%60]=> "01:10:17:36"
Lovely.
