OGG for kafka op_ts 和current_ts相差较大

"op_type":"U","op_ts":"2019-04-30 07:04:36.844662","current_ts":"2019-04-30T15:07:36.778001","pos":"00000016630241124960","before" 发现op_ts 和current_ts相差了8个小时。 关于这两个时间描述： OP_TS and CURRENT_TS are not same. OP_TS : The operation timestamp is the timestamp of the operation from the source trail file.  Since this timestamp is from the source trail it is "fixed".  Replaying the trail file will result in the same timestamp for the same operation. CURRENT_TS : The current timestamp is a timestamp of the current time when formatter processes the current operation  record. This timestamp follows the ISO-8601 format and includes microsecond precision.  Replaying the trail file "will not" result in the same timestamp for the same operation. 这是由属性文件里的goldengate.userexit.timestamp=utc 参数引起。
