ClearPath OS 2200 Series Release 13.2 Software Planning and ...

Open Programming Environment (OPE)
The TZONE configuration variable in OPE is the default time zone for all OPE users. This
configuration variable does not follow the POSIX standard. Because of this, it must be
updated every year to specify that year's correct daylight savings time values. The
default value for time zone is CST6CDT. This will lead to incorrect local time during the
transition between the beginning and end the new DST and the old DST.
The kernel time zone value, TZONE, is described on your online OPE pages at the
location, http://YourOPESystem/opeconfig/WebHelp/kernelpm.htm Refer to the
ClearPath OS 2200 Open Programming Environment (OPE) Configuration Guide for more
details on kernel for TZONE.
To configure your OPE system properly, the days of the year for daylight time transitions
must be added to the time zone variable. These values are described in the following
table.
Year US Central Time US Eastern Time US Pacific Time
US Mountain
Time
2010 CST6CDT,72,310 EST5EDT,72,310 PST8PDT,72,310 MST7MDT,72,310

Edit or add the TZONE variable to your krnl-config element in am$?*ampriv. An example
of the correct setting for the default TZONE setting for the year 2007 follows:
TZONE 'CST6CDT' OLD default variable
change to
TZONE 'CST6CDT,69,307'
The next time your OPE system is rebooted, it will reflect the above change. You may
configure this parameter for the following year as soon as the observance of Daylight
Saving Time has ended for your current year.
