The "int cast" is applied to "diff" value making the resulting long value negative and not properly applying period calculation for the kind of periodicity. Fix is to delete the int cast. Workaround is creating all set of classes allowing us to override the default implementation of this RollingCalendar. <appender name="TechFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="CustomTimeBasedRollingPolicy"> <fileNamePattern>${LOG_DIR}/test-app.%d{yyyy-MM-dd_HH}.log</fileNamePattern> <maxHistory>10</maxHistory> <cleanHistoryOnStart>true</cleanHistoryOnStart> </rollingPolicy> <encoder> <pattern>%d{yyyyMMdd.HHmmss}.%p.%t.%logger{35} %-5level - %msg %n</pattern> </encoder> </appender> public class CustomTimeBasedRollingPolicy<E> extends TimeBasedRollingPolicy<E> { @Override public void start() { setTimeBasedFileNamingAndTriggeringPolicy(new CustomTimeBasedFileNamingAndTriggeringPolicy<>()); super.start(); } } class CustomTimeBasedFileNamingAndTriggeringPolicy<E> extends TimeBasedFileNamingAndTriggeringPolicyBase<E> { private static final String COLLIDING_DATE_FORMAT_URL = CODES_URL + "#rfa_collision_in_dateFormat"; private FileNamePattern fileNamePatternWithoutCompSuffix; @Override public void start() { super.start(); if (!super.isErrorFree()) return; final var fileNamePatternStr = tbrp.getFileNamePattern(); final var fileNamePattern = new FileNamePattern(fileNamePatternStr, this.context); fileNamePatternWithoutCompSuffix = new FileNamePattern(Compressor.computeFileNameStrWithoutCompSuffix(fileNamePatternStr, tbrp.getCompressionMode()), this.context); DateTokenConverter<Object> dtc = fileNamePattern.getPrimaryDateTokenConverter(); if (dtc == null) { throw new IllegalStateException("FileNamePattern [" + fileNamePattern.getPattern() + "] does not contain a valid DateToken"); } if (dtc.getTimeZone() != null) { rc = new CustomTopOfHourRollingCalendar(dtc.getDatePattern(), dtc.getTimeZone(), Locale.getDefault()); } else { rc = new CustomTopOfHourRollingCalendar(dtc.getDatePattern()); } addInfo("The date pattern is '" + dtc.getDatePattern() + "' from file name pattern '" + fileNamePattern.getPattern() + "'."); rc.printPeriodicity(this); if (!rc.isCollisionFree()) { addError("The date format in FileNamePattern will result in collisions in the names of archived log files."); addError(CoreConstants.MORE_INFO_PREFIX + COLLIDING_DATE_FORMAT_URL); withErrors(); return; } if(fileNamePattern.hasIntegerTokenCOnverter()) { addError("Filename pattern ["+fileNamePattern+"] contains an integer token converter, i.e. %i, INCOMPATIBLE with this configuration.
