если у вас есть рельсы, я думаю, ActionView :: Helpers :: DateHelper # distance_of_time_in_words помогает в этом.
require 'rubygems'
require 'action_view'
include ActionView::Helpers::DateHelper
from_time = Time.now
distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour
distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour
distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute
distance_of_time_in_words(from_time, from_time + 15.seconds, true) # => less than 20 seconds
distance_of_time_in_words(from_time, 3.years.from_now) # => over 3 years
distance_of_time_in_words(from_time, from_time + 60.hours) # => about 3 days
distance_of_time_in_words(from_time, from_time + 45.seconds, true) # => less than a minute
distance_of_time_in_words(from_time, from_time - 45.seconds, true) # => less than a minute
distance_of_time_in_words(from_time, 76.seconds.from_now) # => 1 minute
distance_of_time_in_words(from_time, from_time + 1.year + 3.days) # => about 1 year
distance_of_time_in_words(from_time, from_time + 4.years + 9.days + 30.minutes + 5.seconds) # => over 4 years
to_time = Time.now + 6.years + 19.days
distance_of_time_in_words(from_time, to_time, true) # => over 6 years
distance_of_time_in_words(to_time, from_time, true) # => over 6 years
distance_of_time_in_words(Time.now, Time.now) # => less than a minute
В случае относительно текущеговремя, используйте distance_of_time_in_words_to_now
вместо distance_of_time_in_words
.
Если ваше приложение основано на рельсах, просто используйте distance_of_time_in_words
, distance_of_time_in_words_to_now
, time_ago_in_words
в поле зрения.
