Spring-boot log rotations issue with logback - spring

Question

I am working on a spring-boot project and I am using logback and slf4j for logging. Application is deployed on external tomcat and I am using logback 1.1.6 .
I have created an appender with marker , it working fine but rotation policy is not working.
here is the entry from logback.xml
<appender name="FAILED-QUERY"
class="com.xyz.config.HourlyFileAppender">
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator">
<marker>FAILEDQUERY</marker>
</evaluator>
<onMismatch>DENY</onMismatch>
<onMatch>NEUTRAL</onMatch>
</filter>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} - %msg%n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${DEV_HOME}/xyz_otp_logs_failed_query.%d{yyyy-MM-dd-HH-mm}.log
</fileNamePattern>
<!-- <timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
</timeBasedFileNamingAndTriggeringPolicy> -->
</rollingPolicy>
</appender>
<logger name="com.xyz" level="info"
additivity="false">
<appender-ref ref="FAILED-QUERY" />
<!-- <appender-ref ref="STDOUT" /> -->
</logger>
The code for rotating policy is below
public class HourlyFileAppender<E> extends RollingFileAppender<E> {
private static long start = System.currentTimeMillis(); // minutes
private int rollOverTimeInSecond = 60*60;
#Override
public void rollover()
{
long currentTime = System.currentTimeMillis();
int maxIntervalSinceLastLoggingInMillis = rollOverTimeInSecond * 1000;
if ((currentTime - start) >= maxIntervalSinceLastLoggingInMillis)
{
super.rollover();
start = System.currentTimeMillis();
}
}
}
though the same settings for other appender is working fine.
