0.9.7 timezone part2

I see in the PatternLayout class there is a setTimeZone() method, is there
a way i can load my configuration from a properties file, then get the
appenders 1 by 1 and set the timezone on each of them?

We have an application in which the user can change the timezone of the
system through our software, and right now I have to explicitly declare the
timezone in each appender in order to see the properly adjusted time int he
log files.

Thanks,
Jim
