> URL: https://issues.apache.org/jira/browse/LOG4J2-1074

> Add a token in the log format specifier to output the current value of {{System.nanotime()}}.
> We are currently adding the nanotime value to our log messages manually, which we find very useful for troubleshooting unexpected latency, and as a quick-and-dirty data source to feed into performance analysis tools.
> It would be very nice if Log4j could do this for us. It would also be nice to have this in the log format specified, so we can turn it on/off at runtime by editing the Log4j config file.
