-----------------------------------------------------------------------
Note:
1) Time based GC log rotation is not natively supported by JVM. So for the GC
logs, only size based rotation can set the timestamp on the filenames. For all
other log4j generated files, files get rotated every hour or every 256MB
whichever happens first.
2) The configuration is written to STDERR. The same can be achieved with
log4j's marker filter + appender ref but doing it in code is easier (also
attach the timezone info to log line).
3) History logs are now rotated every hour instead of every day
[~sseth] can you please review?
