A DESCRIPTION OF THE PROBLEM :
When TZ environment variable is set to MEZ-1MESZ,M3.5.0,M10.5.0 timezone, SimpleDateFormat.format(Date) is an hour late.

$ setenv TZ MEZ-1MESZ,M3.5.0,M10.5.0

$ java DateUtils

$ date

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -

$ setenv TZ MEZ-1MESZ,M3.5.0,M10.5.0

$ date
Mon Sep 29 22:47:29 MESZ 2008

$ java DateUtils
