#after(time) ⇒ Object

# File 'lib/familia/refinements/time_literals.rb', line 132

def after(time)  = time + seconds

#age_in(unit, from_time = nil) ⇒ Float

Calculates age of timestamp in specified unit from reference time

Examples:

timestamp = 2.days.ago.to_i
timestamp.age_in(:days)         #=> ~2.0
timestamp.age_in('hours')       #=> ~48.0
timestamp.age_in(:days, 1.day.ago) #=> ~1.0

Parameters:

  • unit (String, Symbol) —

    Time unit ('days', 'hours', 'minutes', 'weeks')

  • from_time (Time, nil) (defaults to: nil) —

    Reference time (defaults to Familia.now)

Returns:

  • (Float) —

    Age in specified unit
