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

[Thorbjørn Ravn Andersen]

This system might using be a timezone abbreviation not recognized by the
JVM. 

I spent quite some time a long while back figuring out why an OS/2 JVM was
3.5 hours off.  It turned out that the OS/2 abbreviation for central
European time was not quite what the JVM expected.

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.
