How do i change catalina.out timeformat.

[Magnus Tamm]

Hi. I have two problems.

1) My catalina.out writes different timestamps. Can I fix it and if I can then how? (both formats are wrong.

         1.  Nov 25, 2019 10:22:09 AM

         2.  2019-11-25 09:32:23,326

And the second question is that how do I make them look like this? How do I change my timeformat for catalina.out

I need. 2019-11-25T10:24:46.292+0200 - (yyyy-MM-dd'T'HH:mm:ss.SSSZ)

JIRA logs are based on log4j.properties files. You will have to make changes in log4j files for any changes in logs.

Yes. Time format is described as %d but how do I modify it?

Fixed this part 
2.  2019-11-25 09:32:23,326 now it writes like it should but 

1.  Nov 25, 2019 10:22:09 AM can't find solution for this

Okay. I will answer myself :D 

First part i changed was at log4j.properties 

changed %d to %d{yyyy-MM-dd'T'HH:mm:ss.SSSZ}

Second part I changed at jre/lib/logging.propperties

I commented this line out and changed its values 
java.util.logging.SimpleFormatter.format=%1$tY-%1$tm-%1$tdT%1$tH:%1$tM:%1$tS:%1$tL%1$tz %2$s%n%4$s: %5$s%6$s%n

I also modified conf/logging.properties.

added. 


# formatter attributes = date, source, logger, level, message, thrown
java.util.logging.SimpleFormatter.format = %1$tY-%1$tm-%1$tdT%1$tH:%1$tM:%1$tS:%1$tL%1$tz %2$s%n%4$s: %5$s%6$s%n

and 

1catalina.org.apache.juli.AsyncFileHandler.formatter = java.util.logging.SimpleFormatter.

now it's okay

Found this. Added it to /conf/logging.properties

Also didn't work.
