似乎存在maxHistory參數如何實現的問題。 I（每分鐘 這裏）多次withing的時間間隔翻轉，從而在以下文件：（maxHistory = 3）使用SizeAndTimeBasedFNATP時，最舊的歸檔文件不會被移除，並且存在多個最舊時間間隔的歸檔文件
- trace.log中（有源文件）
- 痕量2013年3月13日-16.14.0.log.zip
- trace-2013-03-13-16.13.0.log.zip
- trace-2013-03-13-16.12.2.log.zip
- 跟蹤2013 -03-13-16.12.1.log.zip
- trace-2013-03-13-16.12.0.log.zip
發生nex時間翻轉，16.13.0.log.zip文件被刪除，而 不是最早的那個（12. {0,1,2}），正如我所預料的那樣。這是 的預期行爲？
