For instance the following config: {code:java} <appender name="LOGBACK" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%date{dd-MM-yyyy'T'HH:mm:ss.n} - %msg%n</pattern> </encoder> </appender> {code} produces output like the following: {code:java} 13-08-2022T16:05:49.211000000 - A sample log message (0) 13-08-2022T16:05:49.213000000 - A sample log message (1) 13-08-2022T16:05:49.213000000 - A sample log message (2) 13-08-2022T16:05:49.213000000 - A sample log message (3) 13-08-2022T16:05:49.213000000 - A sample log message (4) 13-08-2022T16:05:49.213000000 - A sample log message (5){code} As you can see although the pattern asks for nanoseconds after the seconds only the millis are actually output with the nano parts set to zero. A quick look at the code reveals that the {{DateConverter}} gets the timestamp from the ILoggingEvent by calling {{ILoggingEvent#getTimeStamp()}} which gives the timestamp in millis instead of the new {{ILoggingEvent#getInstant()}}.
