Hi everyone,  
I store syslog into elasticsearch and overview data on Kibana.  
I found that the date of @timestamp and \_index doesn't match.  
The \_index is default logstash-\* and it seems would automatically adjust from @timestamp.  
my doubt is that whether the \_index is using UTC, and how to solve it.  
this one looks doesn't match:

following data is match:

Timestamps in Kibana are translated into the browsers timezone, so what zone are you in?

That that looks right.

The first timestamp minus 8 hours would mean the 24th.

Elasticsearch and Logstash use UTC anyway, so it won't do anything.
