Hi,

We have servers all over the glob, we need to save Wowza log files with UTC time.

Some one know how we can do it?

Thanks,

Eliran

Eliran,

Take a look at the /conf/log4j.properties file. I think you can probably accomplish this with Appender.DatePattern:

[code[

log4j.appender.serverAccess.DatePattern=’.'yyyy-MM-dd

Looking around, I it think might also involve Appender.layout.ConversionPattern

Search for “log4j utc gmt datepattern conversionpattern”

Hi rrlanham,

Thanks for the fast replay but i find a way using java parameters.

[http://publib.boulder.ibm.com/infoce…e/adrtzval.htm](http://publib.boulder.ibm.com/infoce...e/adrtzval.htm)

What I did is add the

```auto
-Duser.timezone=UTC 

```

to the stratup.bat file

and to the WowzaMediaServer-Service.conf file i added this line under “# Java Additional Parameters”

wrapper.java.additional.#=-Duser.timezone=UTC

where #=the next number, in my case 8.

Thanks

The best place to add it is in the setenv.bat file. A few changes have been made in 3.6 so now all configuration items are the same between Linux/Windows/Mac so making it easier to manage.

In the setenv.bat file

after

```auto
rem Uncomment to force Java to use specific language settings
rem set JAVA_OPTS=%JAVA_OPTS% -Duser.language=en -Duser.country=US -Dfile.encoding=Cp1252

```

add

```auto
set JAVA_OPTS=%JAVA_OPTS% -Duser.timezone=UTC

```

This should add it to the Java options when Wowza starts up.

Andrew.

Hi,

I tried this on 3.6.1 by adding -Duser.timezone=UTC into startup.bat, but log files are stillshowing BST.

1st 4 lines of startup.bat

@echo off

SETLOCAL ENABLEEXTENSIONS

-Duser.timezone=UTC

set runmode=standalone

Any ideas what I am doing wrong?

Thanks Andrew that worked OK.

I will be running as a service in production, do I need to add this to WowzaMediaServer-Service.conf file?
