Thank you Jan-Olav, but sorry, should have read the documentation first.

I achieve what I want just by adding the file property

  <appender name="filesystem" class="ch.qos.logback.core.rolling.RollingFileAppender">

                 <file>log.txt</file>

    <encoder>

      <pattern>%d %5p [%t] %c{1} - %msg%n</pattern>

    </encoder>

                               <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

                                 <fileNamePattern>log-%d{yyyy-MM-dd_HH-mm}.txt.%i</fileNamePattern>                                                               

                                 <TimeBasedFileNamingAndTriggeringPolicy  class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">

                                               <maxFileSize>1000MB</maxFileSize>

                                 </TimeBasedFileNamingAndTriggeringPolicy >                               

                               </rollingPolicy>   

  </appender>

How about :

       String activeLogFile = "a file name of your choice";
        LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
        RollingFileAppender<ILoggingEvent> appender = new RollingFileAppender<ILoggingEvent>();
        appender.setContext(loggerContext);
        appender.setFile(activeLogFile);

        String archiveDir = "a directory of your choice"
        createIfNeeded(archiveDir);
        TimeBasedRollingPolicy<ILoggingEvent> timePolicy = new TimeBasedRollingPolicy<ILoggingEvent>();
        timePolicy.setFileNamePattern(archiveDir + patternFor("%d{yyyy-MM-dd,aux}/%d{yyyy-MM-dd-hh}"));  // hourly
       .....

Hallo.

Is it possible to configure a TimeBasedRollingPolicy so that the file that it is being logged to does not

have any date in the filename, but the rolled over files has.

Thanks
