it's a small code misstake which could be saw in the attachment. because of this, timestamp of LogginEventVo will be zero.
in my situation,i use SocketAppender and SimpleSocketServer to achieve the goal of remote log collection. when i do my test, the time in the log file at the server side is incorrect. the time is 1970-01-01 08:00:00.000. after researching, it turns out to be above problem.
