Summary :
This SAP Note outlines the manual and automated procedures to adjust system time for daylight saving changes on IBM eServer iSeries and DB2 UDB for iSeries, distinguishing between OS/400 V5R2M0 and i5/OS V5R3M0 versions. For older systems, manual adjustment of QTIME and QUTCOFFSET is required, whereas newer versions automatically update based on QTIMZON. SAP Kernel changes, affecting time settings through environment variables PASE_TZ or TZ, are explained with detailed instructions for transitioning times, emphasizing system inactivity to prevent time discrepancies during adjustments.
