Sometimes/Most of the time TimebasedRolling does not work.

• Log files have 1970-01-01 for %d in the name.
• Log files contain only one line i.e. file gets overwritten with every log statement.
• restart seems to help, probably till midnight
• did not happen with older versions SLF4J 1.3 and (probably) Logback 0.9.3

Used in combination with jcl-over-slf.
