[logback-dev] [JIRA] (LOGBACK-1346) Set daily rollovers without full date together in the fileNamePattern

[Martin Grajcar]

I wanted to use %d{yyMM}/%d{dd} and it didn't work for the same reason, but
%{yyMM/dd} works fine. No idea if it applies to your case.

I don't understand why only the first date format gets considered for
rollover. IMHO it's a bug, while taking the *union of all date specifiers*
would be just right.
