Hi,

I would like to convert date in string to date in integer. In below example I would like format of "TS" to be similar to that of @timestamp

{  
"type" =\> "perf",  
.............  
"@timestamp" =\> 2017-04-29T01:25:21.279Z,  
.............  
"TS" =\> "Fri Apr 28 16:16:29 2017"  
}

My /etc/logstash/conf.d/logstash.conf has

input {  
file {  
path =\> "/var/www/html/processed/perf.csv"  
type =\> "perf"  
start\_position =\> beginning  
sincedb\_path =\> "/dev/null"  
ignore\_older =\> 0  
}  
}

filter {  
if [type] == "perf" {  
csv {  
separator =\> ","  
columns =\> ['TS','CAPACITY']  
convert =\> {  
'CAPACITY' =\> 'integer'  
}  
}

```
    date {
        match => ["TS", "dd/MMM/YYYY:HH:mm:ss Z"]
    }
}

```

}

output {  
if [type] == "perf" {  
elasticsearch {  
hosts =\> "localhost:9200"  
action =\> "index"  
index =\> "lstash-%{+YYYY.MM.dd}"  
}  
}  
stdout { codec =\> rubydebug }  
}

I am getting following parse error and also TS not converted. Tried multiple methods mentioned in various discussions nothing worked.

{  
"type" =\> "perf",  
..........  
"tags" =\> [  
[0] "\_dateparsefailure"  
],  
"@timestamp" =\> 2017-04-29T01:30:53.806Z,  
..........  
"TS" =\> "Fri Apr 28 16:13:49 2017"  
}

Made it working. Since "TIMESTAMP" is "Fri Apr 28 16:16:29 2017"  
Filter should have been:

```
    date {
        match => ["TS", "EEE MMM dd HH:mm:ss YYYY"]
        timezone => "UTC"
        remove_field => "timestamp"
    }

```

Nice documentation. Thanks

Does not match this at all;

> [@sraghu1980](#):
>
> match =\> ["TS", "dd/MMM/YYYY:HH:mm:ss Z"]

You need to recheck that pattern so that it actually matches.
