If the New Day procedure starts before 1:00 am, do not take any special action. The New Day procedure runs only once.
If the New Day procedure starts exactly at 1:00 a.m., do not adjust the CLOCKnn member at 1:00 a.m., to avoid another New Day process. A second New Day procedure requires manual intervention. It is advisable to wait a few minutes (until 2:05 a.m., for example) and then adjust the CLOCKnn member.
If the New Day procedure is scheduled to begin between 1:00 a.m. and 2:00 a.m., do one of the following:
wait at least one full hour after the daily run begins, and then adjust the CLOCKnn member (the New Day procedure will already have ended)
or
update the CLOCKnn member before New Day processing begins.
For example, if the New Day procedure is scheduled to begin at 1:45 a.m., adjust the CLOCKnn member at about 1:40 a.m. If this is not done by 1:40 a.m., wait until about 2:50 a.m. and then adjust the CLOCKnn member.
If the New Day procedure is scheduled to begin after 2:00 a.m., do not take any special action.
