instance method
advance
Ruby on Rails 7.0.10
Since v3.0.20Signature
advance(options)Uses Date to provide precise Time calculations for years, months, and days according to the proleptic Gregorian calendar. The options parameter takes a hash with any of these keys: :years, :months, :weeks, :days, :hours, :minutes, :seconds.
Time.new(2015, 8, 1, 14, 35, 0).advance(seconds: 1) # => 2015-08-01 14:35:01 -0700 Time.new(2015, 8, 1, 14, 35, 0).advance(minutes: 1) # => 2015-08-01 14:36:00 -0700 Time.new(2015, 8, 1, 14, 35, 0).advance(hours: 1) # => 2015-08-01 15:35:00 -0700 Time.new(2015, 8, 1, 14, 35, 0).advance(days: 1) # => 2015-08-02 14:35:00 -0700 Time.new(2015, 8, 1, 14, 35, 0).advance(weeks: 1) # => 2015-08-08 14:35:00 -0700
Just like Date#advance, increments are applied in order of time units from largest to smallest. This order can affect the result around the end of a month.
