I have 2 date field in a CSV data, formatted as ==\> MM/dd/YY HH:mm

How can i change the format to ==\> YYYY/MM/dd HH:mm:ss  
when am indexing it using logstash ?

I want to save the field as date in elastic, not as a string or text. How can i do that ?

When i tried date match as below, field become string in elastic

date {  
match =\> ["Incident\_Close\_Date" , "MM/dd/YY HH:mm"]  
timezone =\> "Etc/UTC"  
}  
date {  
match =\> ["Incident\_Create\_Date" , "MM/dd/YY HH:mm"]  
timezone =\> "Etc/UTC"  
}
