       The  bson_append_date_time() function shall append a new element to a bson document containing a date and
       time with no timezone information. value is assumed to be in UTC format of milliseconds  since  the  UNIX
       epoch. valueMAY be negative.

       • bson: A bson_t.

       • key: An ASCII C string containing the name of the field.

       • key_length: The length of key in bytes, or -1 to determine the length with strlen().

       • value: The date and time as specified in milliseconds since the UNIX epoch.

       Returns  true  if the operation was applied successfully. The function will fail if appending value grows
       bson larger than INT32_MAX.
