Detailed Description

Represents a MySQL temporal value (DATE, TIME, DATETIME or TIMESTAMP) - an extension to the ECMA set of JSON scalar types, types J_DATE, J_TIME, J_DATETIME and J_TIMESTAMP respectively.

The method field_type identifies which of the four it is. Currently, this is an abstract class with two child classes: Json_datetime and Json_time.
