-------------------------------------------------------------
It's still not working for me, is it because I'm using a
{{RollingRandomAccessFileAppender}} instead of a {{RollingFileAppender}}?
*Update:* changing the appender "works", but the files have the time of the
next interval. I have a {{TimeBasedTriggeringPolicy}} with {{interval}} of 1
(minute) and {{modulate}} does not seem to have an effect here.
For example, it's *10:23:40* when starting the application with a pattern of
{{test.%d\{HH-mm\}.log}}:
# A file {{test.10-23.log}} is created and logs events at that time, as
expected.
# At *10:24:00*, no new files are created and logging is still appended to he
previous file. _This is not expected._
# At *10:25:00*, a file {{test.10-24.log}} is created and starts appending
entries for minute 10:25.
# At *10:26:00*, a file {{test.10-25.log}} is created and will contain all
entries for minute 10:26.
I'd expect the time of the log entry to match the time of the filename, so that
a log event happening at 10:25:32 would be in {{test.10-25.log}} instead of
{{test.10-24.log}}.
Am I missing something?

> Ability to change the fileName dynamically in RollingFileAppender

> Key: LOG4J2-1185
> URL: https://issues.apache.org/jira/browse/LOG4J2-1185
> Project: Log4j 2
> Issue Type: New Feature
> Components: Appenders
> Affects Versions: 2.1
> Reporter: Dhwaneet Bhatt
> Assignee: Ralph Goers
> Fix For: 2.8
>
>
> Right now RollingFileAppender rolls over the current file with fileName to
> the one generated by FilePattern. However, logging always continues in the
> same fileName i.e. fileName once created cannot be changed.
> Property Substitution is only once during initialization, fileName is never
> changed after RollingFileManager is initialized. The RollingFileManager is
> very tightly tied up to the fileName attribute.
> Consider that I want to name my log files like this using RollingFileAppender:
> mylog-2015-10-30.log
> mylog-2015-10-29.log
> mylog-2015-10-28.log
> There is no good way to achieve this, because even after rolling over the
> file, the fileName would still remain the same. If I initialized my fileName
> using $\{date:yyyy-MM-dd\}, date would be substituted only once during
> initialization and it would never change, always continue to log in the same
> log file (until I restart my application).
