advance(options) click to toggle source

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.

# File lib/leap_cli/core_ext/time.rb, line 14
def advance(options)
  unless options[:weeks].nil?
    options[:weeks], partial_weeks = options[:weeks].divmod(1)
    options[:days] = options.fetch(:days, 0) + 7 * partial_weeks
  end

  unless options[:days].nil?
    options[:days], partial_days = options[:days].divmod(1)
    options[:hours] = options.fetch(:hours, 0) + 24 * partial_days
  end

  d = to_date.advance(options)
  d = d.gregorian if d.julian?
  time_advanced_by_date = change(:year => d.year, :month => d.month, :day => d.day)
  seconds_to_advance = options.fetch(:seconds, 0) +
                       options.fetch(:minutes, 0) * 60 +
                       options.fetch(:hours, 0) * 3600

  if seconds_to_advance.zero?
    time_advanced_by_date
  else
    time_advanced_by_date.since(seconds_to_advance)
  end
end
change(options) click to toggle source

Returns a new Time where one or more of the elements have been changed according to the options parameter. The time options (:hour, :min, :sec, :usec) reset cascadingly, so if only the hour is passed, then minute, sec, and usec is set to 0. If the hour and minute is passed, then sec and usec is set to 0. The options parameter takes a hash with any of these keys: :year, :month, :day, :hour, :min, :sec, :usec.

# File lib/leap_cli/core_ext/time.rb, line 53
def change(options)
  new_year  = options.fetch(:year, year)
  new_month = options.fetch(:month, month)
  new_day   = options.fetch(:day, day)
  new_hour  = options.fetch(:hour, hour)
  new_min   = options.fetch(:min, options[:hour] ? 0 : min)
  new_sec   = options.fetch(:sec, (options[:hour] || options[:min]) ? 0 : sec)
  new_usec  = options.fetch(:usec, (options[:hour] || options[:min] || options[:sec]) ? 0 : Rational(nsec, 1000))

  if utc?
    ::Time.utc(new_year, new_month, new_day, new_hour, new_min, new_sec, new_usec)
  elsif zone
    ::Time.local(new_year, new_month, new_day, new_hour, new_min, new_sec, new_usec)
  else
    ::Time.new(new_year, new_month, new_day, new_hour, new_min, new_sec + (new_usec.to_r / 1000000), utc_offset)
  end
