VijayaKumar Guddeti commented on LOG4J2-1242:
---------------------------------------------

Sharing below the appender which we used in the project, using this appender the Rollover
at everyday midnight is NOT occurred. Please notice the finest granularity here in the date
pattern is SSS, also the rollover at midnight is NOT happening when finest granularity is
mm or ss. 

But successful rollover at midnight when date pattern having finest granularity as dd or HH

<RollingFile name="DNSTimingReportAppender" fileName="./logs/TestReport.csv" filePattern="./logs/DNSTimingReport-%d{yyyy-MM-dd-HHmmssSSS}.csv"
append="true" bufferedIO="fase" />
	<Policies>
		<TimeBasedTriggeringPolicy interval="86400000" modulate="true"  />
		<SizaasedTriggeringPolicy size="60 MB" />
	</Policies>
</RollingFile>


could you please share your thoughts.

> Rollover fails to happen over midnight of everyday when 'date pattern' having mm or ss
or SSS as the finest granularity, but working as expected when it is dd or HH. It means log4j2
(TimeBasedTiggeringPolicy) 'modulate' property is not functioning properly with mm or ss or
SSS as most specific in 'date pattern'.
> Tested with below scenarios, roll over did NOT had at midnight: 
> 1. RollingFile - filePattern="/app/rolledoverlogs/%d{yyyy-MM-dd.HHmm}" 
> TimeBasedTriggeringPolicy - interval = 1440, modulate = true
> 2. RollingFile - filePattern="/app/rolledoverlogs/%d{yyyy-MM-dd.HHmmss}" 
> TimeBasedTriggeringPolicy - interval = 86400, modulate = true
> 3. RollingFile - filePattern="/app/rolledoverlogs/%d{yyyy-MM-dd.HHmmss.SSS}" 
> TimeBasedTriggeringPolicy - interval = 86400000, modulate = true
> Tested with below scenarios, roll over is happening at midnight: 
> 1. RollingFile - filePattern="/app/rolledoverlogs/%d{yyyy-MM-dd.HH}" 
> TimeBasedTriggeringPolicy - interval = 24, modulate = true
> 2. RollingFile - filePattern="/app/rolledoverlogs/%d{yyyy-MM-dd}" 
> TimeBasedTriggeringPolicy - interval = 1, modulate = true
