Hi,

I am new with ELK concepts, I need a help with TIME pattern. The value from input is in HH:mi:ss format (00:01:05) and in elasticsearch its recognized as string.  
Can elasticsearch be forced to recognize this as date or time format so that I can use this field for aggregations?  
I want to use this field values for creating table wth max, min and avg values.

Logstash entry  
if [type] == "testing\_pattern" {  
grok {  
patterns\_dir =\> ".\software\patterns"   
match =\> {"message" =\> ["%{TIME:time\_test}"]}  
}  
date {  
match =\> ["time\_test", "HH:mm:ss"]  
#timezone =\> "UTC"  
}  
}

Please let me know if you need any further details?
