ago(time = ::Time.current)

Reads best without arguments: 10.minutes.ago

Also aliased as: until

  time - self
end
byte()
Alias for: bytes
bytes()

Enables the use of byte calculations and declarations, like 45.bytes + 2.6.megabytes

Also aliased as: byte

Numbers are not duplicable:

3.duplicable? # => false
3.dup         # => TypeError: can't dup Fixnum

end
second()
Alias for: seconds
seconds()

Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.

These methods use Time#advance for precise date calculations when using #from_now, ago, etc. as well as adding or subtracting their results from a Time object. For example:

# equivalent to Time.current.advance(months: 1)
1.month.from_now

# equivalent to Time.current.advance(years: 2)
2.years.from_now

# equivalent to Time.current.advance(months: 4, years: 5)
(4.months + 5.years).from_now

While these methods provide precise calculation when used as in the examples above, care should be taken to note that this is not true if the result of `months', `years', etc is converted before use:

# equivalent to 30.days.to_i.from_now
1.month.to_i.from_now

# equivalent to 365.25.days.to_f.from_now
1.year.to_f.from_now

In such cases, Ruby's core Date and Time should be used for precision date and time arithmetic.

Also aliased as: second
# File activesupport/lib/active_support/core_ext/numeric/time.rb, line 34
def seconds
  ActiveSupport::Duration.new(self, [[:seconds, self]])
end
since(time = ::Time.current)

Reads best with argument: 10.minutes.since(time)

Also aliased as: from_now
# File activesupport/lib/active_support/core_ext/numeric/time.rb, line 74
def since(time = ::Time.current)
  ActiveSupport::Deprecation.warn "Calling #since or #from_now on a number (e.g. 5.since) is deprecated and will be removed in the future, use 5.seconds.since instead"
  time + self
end

Alias for: terabytes
terabytes()
Also aliased as: terabyte
# File activesupport/lib/active_support/core_ext/numeric/bytes.rb, line 30
def terabytes
  self * TERABYTE
