Find out how to use a time maintenance application to make the necessary adjustments to your system time.
If you want to use a time maintenance application to synchronize your system time with an external time source, you need to configure the time maintenance application on each system. You can use the SNTP time maintenance application or an application of your own.
For your time maintenance application to make the necessary time adjustments, your system must meet the proper software and hardware requirements. To make time adjustments, you must be using a version of i5/OS™ V5R3 or later with V4R5 or later hardware.
