NonStop Operating System
Beginning with 2007, daylight saving time (DST) for the United States changes. The
NonStop Operating System (T9050) is enhanced to reflect the DST changes for 2007
and later.
Migration
•
If the DST option is TABLE and you want to implement the new U.S. algorithm,
follow one of these two steps:
°
Delete the DST transition values for 2007 and later by using the
DST_TRANSITION_DELETE_ Guardian procedure call and add the new DST
transition values by using the DST_TRANSITION_ADD_ Guardian procedure
call. You can also use TACL statements to add the DST transition values.
°
Modify the existing values with the new DST transition values for 2007 and
later by using the DST_TRANSITION_MODIFY_ Guardian procedure call.
•
If you are outside of the United States and currently are using the USA66 option
but your countries are not adopting the new U.S. algorithm, follow these steps:
°
Change the DST option to TABLE.
°
Reset the processors and load the system.
°
Add the new DST transition values for 2007 and later by using the
DST_TRANSITION_ADD_ Guardian procedure call. You can also use TACL
statements to load the DST table with the DST transition values.
•
If the DST option is USA66, reset the processors and load the system to reflect the
new DST transitions.
For details on the Guardian procedure calls, see the Guardian Procedure Calls
Reference Manual.
Fallback
If the DST transition for 2007 does not display the correct time change, switch to the
TABLE option and add the DST transition entries into the DST table for 2007 and later.
If you use the TABLE option, you do not need to fall back to a previous SPR, because
