Public Instance Methods

as_json(*) click to toggle source

Methods Time#as_json and Time.json_create may be used to serialize and deserialize a Time object; see Marshal.

Method Time#as_json serializes self, returning a 2-element hash representing self:

require 'json/add/time'
x = Time.now.as_json
# => {"json_class"=>"Time", "s"=>1700931656, "n"=>472846644}

Method JSON.create deserializes such a hash, returning a Time object:

Time.json_create(x)
# => 2023-11-25 11:00:56.472846644 -0600

# File json/lib/json/add/time.rb, line 36
def as_json(*)
  nanoseconds = [ tv_usec * 1000 ]
  respond_to?(:tv_nsec) and nanoseconds << tv_nsec
  nanoseconds = nanoseconds.max
  {
    JSON.create_id => self.class.name,
    's'            => tv_sec,
    'n'            => nanoseconds,
  }
end

to_json(*args) click to toggle source

Returns a JSON string representing self:

require 'json/add/time'
puts Time.now.to_json

Output:

{"json_class":"Time","s":1700931678,"n":980650786}
