Hi

I want to output the file using current time just like the config below.  
output {  
file {  
path =\>"/home/test/%{+YYYYMMdd}/nginx\_%{+YYYYMMdd\_HH}.log"  
}  
}

the filename generated use the UTC timezone time, But I want to ouput the filename with my local time zone(Asia/Beijing)  
e.g my local current time is "2016-12-23 17:44"

run the config file above, the filename is "nginx\_20161223\_09.log"

how can I get the filename using my timezone,just like this "nginx\_20161223\_17.log"???

Thanks!!!

UTC is used and this isn't configurable. What you can do (although I think it's a mistake) is to use a ruby filter to create a `@metadata` field containing the date you want and then reference _that_ field in the file output's path configuration.

I'm afraid I don't have a code snippet handy. What part are you having trouble with?
