Hi, my centralized syslog server is in timezone EST, logstash reads /var/log/messages (file input) on this server. Some of the servers sending syslog data are in timezone CST. If I do any searches 1 hour or less old, I do not see any data from the servers in CST.

cat /etc/logstash/conf.d/10-syslog.conf

filter {  
if [type] == "syslog" {  
grok {  
match =\> { "message" =\> "%{SYSLOGTIMESTAMP:syslog\_timestamp} %{SYSLOGHOST:syslog\_hostname} %{DATA:syslog\_program}(?:[%{POSINT:syslog\_pid}])?: %{GREEDYDATA:syslog\_message}" }  
add\_field =\> ["received\_at", "%{@timestamp}"]  
add\_field =\> ["received\_from", "%{host}"]  
}  
syslog\_pri { }  
date {  
match =\> ["syslog\_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]  
}  
}  
}

For messages from CST servers, I see received\_at showing time in EST, and the one hour difference as shown from syslog\_timestamp.

Also using filebeat to send data to above logstash, all its timestamps are in CST.

How can I get the data from CST servers to display as well as the data from EST servers?

Store the local [timezone name](http://joda-time.sourceforge.net/timezones.html) in a field via Filebeat (you'll have to hardcode it into the Filebeat configuration), then reference that field in the date filter:

```auto
date {
  match => ...
  timezone => "%{tz}" # or whatever you call the field
}

```
