Hi,  
I have json like this  
{system: {time:2017-05-15 12:12:33,version....}...}

I have config for logstash like this

date {  
match =\> ["system.time", "yyyy-MM-dd HH:mm:ss"]  
target =\> "@timestamp"  
}

But this is not matching time

Please help me on this.

match =\> ["[system\_test][test\_time]" , "yyyy-MM-dd HH:mm:ss" ]
