Hi ,

I have a field by the name "create\_date" , the field format is: "MM/DD/YYYY" for example: 05/29/2016.  
I want to update timestamp as create\_date  
Which match format I need to put when I use Logstash ?

filter{  
date {  
match =\> ["create\_time", "??????"]  
target =\> "@timestamp"  
}  
}

BR,  
Chen

MM/dd/yyyy or MM/dd/YYYY.

Please familiarize yourself with the documentation of these patterns: [http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html](http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html)
