ruby 日期 关键字: ruby time
Ruby代码
difference = Time .now - time seconds = difference % 60 difference = (difference - seconds) / 60 minutes = difference % 60 difference = (difference - minutes) / 60 hours = difference % 24 difference = (difference - hours) / 24 days = difference % 7 difference = (difference - days) / 7 weeks = difference % 4 difference = (difference - weeks) / 4 months = difference % 12 years = (difference - months) / 12 puts "(#{years} years , #{months} months ,#{weeks} weeks, #{days} days, #{hours}:#{minutes}:#{seconds})"rail 实现
Ruby代码
def distance_of_time_in_words(from_time, to_time = 0, include_seconds = false ) from_time = from_time.to_time if from_time.respond_to?( :to_time ) to_time = to_time.to_time if to_time.respond_to?( :to_time ) distance_in_minutes = (((to_time - from_time).abs)/60).round distance_in_seconds = ((to_time - from_time).abs).round case distance_in_minutes when 0..1 return (distance_in_minutes == 0) ? 'less than a minute' : '1 minute' unless include_seconds case distance_in_seconds when 0..4 then 'less than 5 seconds' when 5..9 then 'less than 10 seconds' when 10..19 then 'less than 20 seconds' when 20..39 then 'half a minute' when 40..59 then 'less than a minute' else '1 minute' end when 2..44 then "#{distance_in_minutes} minutes" when 45..89 then 'about 1 hour' when 90..1439 then "about #{(distance_in_minutes.to_f / 60.0).round} hours" when 1440..2879 then '1 day' when 2880..43199 then "#{(distance_in_minutes / 1440).round} days" when 43200..86399 then 'about 1 month' when 86400..525599 then "#{(distance_in_minutes / 43200).round} months" when 525600..1051199 then 'about 1 year' else "over #{(distance_in_minutes / 525600).round} years" end end中文实现:
