How can I change unifier.log from SizeBase to TimeBase?

my unifier.log's setting is SizeBasedTriggeringPolicy.

And I want to change unifier.log from SizeBasedTriggeringPolicy to TimeBasedTriggeringPolicy for get logs generated per day.

So i modified "log4j2.properties" but it is not work.

How do I fix it for it to work?

------log4j2.properties------

appender.unifier_log.type = RollingFile

appender.unifier_log.name = unifier_log

appender.unifier_log.fileName=/log/unifier/Unifier.log

appender.unifier_log.filePattern=/log/unifier/Unifier-%i.log.gz

appender.unifier_log.layout.type = PatternLayout
