Issue Type: Bug Bug
Affects Versions: 1.0.6
Assignee: Logback dev list
Components: logback-core
Created: 16/Aug/12 3:10 PM
Description: We have boilerplate time-based rolling filer appender (see below). At midnight, rollover occurs correctly. But, sometime during the next few hours, a switch occurs and from then all logs are being written to the previous day's log file.

I have seen the rollover at midnight and can confirm that at that point logging is correct. I have not observed the point at which the switch-back occurs but it is occurring each time.


  <appender name="DailyRollingFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>teamwork.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- daily rollover -->
      <fileNamePattern>teamwork.log.%d</fileNamePattern>

      <!-- keep 30 days worth of history -->
      <maxHistory>30</maxHistory>
     
      <append>true</append>
     
    </rollingPolicy>

    <encoder>
       <pattern>%-5level [%thread] %d{HH:mm:ss.SSS} [%logger{0}] - %msg%n</pattern>
    </encoder>
 </appender>
