Hi,

Following is the timezone setting documentation for Logstash Date filter.  
What is meant by **platform default** in the description? Does it mean the timezone of the server on which the Logstash is running?

```auto
Timezone

Value type is string
There is no default value for this setting.

Specify a time zone canonical ID to be used for date parsing. 
The valid IDs are listed on the (Joda.org available time
zones page)[http://joda-time.sourceforge.net/timezones.html]. 
This is useful in case the time zone cannot be extracted 
from the value, and is not the platform default. If this is not 
specified the platform default will be used. Canonical ID is 
good as it takes care of daylight saving time for you.
For example, America/Los_Angeles or Europe/France are valid IDs.

```

@warkolm  
Thanks Mark.  
But is it the same case for **curl** command?  
Does curl has mechanism for timezones?

Not sure, `man curl` should show you.

But, why does that matter?

Because when we run curl from one timezone and es in another timezone, then which timezone does document is considered?
