[jira] [Comment Edited] (LOG4J2-1883) Timestamp does not seem to support microseconds level

No, none of those help. The first two are just formatting methods. As its name implies, currentTimeMillis gets the time in milliseconds, not microseconds. nanoTime will get the number of nanoseconds since the JVM started, which is useless for displaying wall clock time. If you are somehow trying to concatenate the nanoseconds to the milliseconds the result doesn't make any sense since they don't have a comment point of reference and there is no way to create one.

>          Issue Type: Bug
>          Components: Configurators

> Used log4j and 'log4j2.xml' to configure timestamp format as:
> {code}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="WARN">
>     <Appenders>
>         <Console name="Console" target="SYSTEM_OUT">
>             <PatternLayout pattern="[%d{yyyy-MM-dd'T'HH:mm:ss.SSSXXX}{UTC}][%level][%logger{36}]:%msg%n"/>
>         </Console>
>     </Appenders>
>     <Loggers>
>         <Root level="DEBUG">
>             <AppenderRef ref="Console"/>
>         </Root>
>     </Loggers>
> </Configuration>
> {code}
> This pattern produces the time stamp as:
> {code}
> [2017-03-29T13:55:28.363000][null]:[Thread-1]: - <message>
> {code}
> The desired output is:
> {code}
> [2017-03-29T13:55:28.363701-07:00][null]:[Thread-1]: - <message>
> {code}
> Different versions of JDKs were tried including JDK 1.8. It does not seem to make any difference in the outcome.
> Is there a way to get the desired time stamp through pattern matching configuration in the '*.xml' file?
