钉钉获取审批实例列表

钉钉获取审批实例列表  开始时间筛选条件不生效
例如 1518225064=2018-02-10 XX:XX:XX 现在时间 减去 3600 时间



$option = array(
     "process_code"=>$processCode,
    "start_time"=>time()-3600,
    "size"=>10,
    "cursor"=>0
);
查询出的数据
第一条的数据时间就不对了
[0] => Array
                (
                    [approver_userid_list] => Array
                        (
                            [0] => 104852164726166615
