5.2 but some customers may not have applied the fixes. Sign up for
We customized weekly
recommend you verify all your AIX systems have the fix newsletter from IBM
applied.
Without the fix applied, the daylight savings time
change
may not occur properly which could cause time sensitive
applications to malfunction.
Run lslpp -L bos.rte.date and compare the output with
the
following list. The fileset should be at or above the
level
in this list.
AIX 4.3.3 bos.rte.date 4.3.3.77
AIX 5.1 bos.rte.date 5.1.0.26
AIX 5.2 bos.rte.date 5.2.0.1
The fixes are available for immediate downloading at the
AIX Fix Delivery Center located at
https://techsupport.services.ibm.com/server/aix.fdc
IMPORTANT
The fix corrects the programs that created the error but
does not fix the variable setting itself. After applying
the fix you must take the following actions.
Action 1
Reset the time zone variable TZ if "echo $TZ" output
includes one or more commas. To reset the variable, run
smitty chtz.
Action 2
If you reset the time zone variable because it included
one
or more commas, then either refresh the cron daemon and
restart all applications that read the time zone
environment variable -or- reboot the system.
Reference information:

5.1 APAR IY34203 SMITTY CHTZ APPENDING 2 COMMAS AFTER TZ

ITEM 2
IBM relased a fix in March 2003 for AIX 5.2 but some
customers may not have applied the fix. We recommend you
verify all your AIX systems have the fix applied.
Without the fix applied, systems that use daylight
savings
time offsets may not properly change time at the correct
time. This could cause time sensitive applications to
malfunction. An offset in DST is not widely used. You do
not need to apply the fix if you do not use a DST
offset.
Run lslpp -L bos.rte.libc and compare the output with
the
following list. The fileset should be at or above the
level
in this list.
AIX 5.2 bos.rte.libc 5.2.0.10
