[logback-user] TimeBasedRollingPolicy - old logs present in current file

[Pradnya Gawade]

Hi David,

Thanks for the reply. I did not try with the latest version and will
update once I do it. But as I mentioned it used work with the same
logback version before my logging configuration was simpler.

Thanks,
Pradnya
