Major Description
because of the app.log file is never delete, app.log file create time never change.
first day all log write in app.log
second day app.log content copy to app-first day.log, second day log write in app.log
third day app.log content copy to app-first day.log, third day log write in app.log
debug the code AbstractRolloverStrategy#getEligibleFiles:91 call PatternProcessor#formatFileName:257 create file use prevFileTime
prevFileTime is set at RollingFileManager#initialFileTime:683 use file creationTime.
I think third day app.log content should copy to app-second day.log. the code should delete app.log file then create file or use app.log last modify time
