Ralph Goers commented on LOG4J2-1883:
-------------------------------------
The current limitations are that the only real time clock available in Java is
System.currentTimeMillis(). That gives the number of microseconds since Jan 1,
1970. System.nanoTime() gives you the number of nanoseconds since the JVM
started. Since there is no way to know what the real time in nanoseconds was
when the JVM started there is no way to correlate them. In Java 9,
java.time.Clock will have access to the system clock with whatever precision it
provides, so using a LocalDateTime in Java 9 should allow us to get the time
with the desired precision.

> Key: LOG4J2-1883
> URL: https://issues.apache.org/jira/browse/LOG4J2-1883
> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators
> Environment: Linux with any JDK including JDK1.8
> Reporter: Madhava Dass
> Priority: Critical
>
> 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?
