[logback-user] Appender and zipping file

Hi Guys, I'm using the RollingOverAppender with the TimeBasedRollingPolicy that also automatically zips the file. However when running it for, say, 24 hours with rolling policy of one hour only 23 files get zipped. The same applies if rolling policy is set to a minute; the last file never gets zipped. Anyway I just want to find out if there is a way to tell the RollingoverAppender that the very last file also needs to be zipped even if the full hour hasn't passed yet. Thanks for any info. Greg.
