[logback-user] Localtime(from server) to be printed instead of GMT

I'm pretty sure that the default is whatever timezone Java thinks it is 
running under.  Normally this is the local timezone, but I have seen 
setups where some of Java's time zone information files have been 
removed, which causes Java to default to GMT.  Java out of the box does 
not do that.  What version of the JDK are you using and has it been 
modified or is it direct from Oracle or other vendor?

By default Java does not read a timezone from /etc/localtime, which of 
course does not exist under all OSes.  I do not know whether or not 
logback has features to customize timestamps beyond what you are using. 
  It may be that it hasn't been considered necessary since there are 
many opportunities to customize Java.

So your first step is to figure out why Java is defaulting to GMT. 
Again, that is not the normal behavior.
