Hi,
If you want to modify the DST time which will be the time wou want to
display in the system , you can do it using /etc/localtime . You can
find a set of TimeZone files in your system . or you can create your
own customized timezone file using a ZIC timezone conpiler . Where you
need to specify some Rules and Zones. Replace the /etc/localtime file
with the file generated from the ZIC compiler , you will get the
updated localtime with DST offset.
