Daylight Saving Time (DST) change with z/VSE

As every year I want to give some references about z/VSE and the time change that will come in March. E,g, for US the change to Daylight Saving Time (DST) is Sunday, March 10, 2019, for Germany March 31, 2019. The clock is turned forward one hour at 2 a.m.
A local time change forward has normally no effect on subsystem operation. It may have an impact on accounting, however. A local time change backwards could affect subsystems and accounting routines more severely. Therefore I recommend to IPL the z/VSE system for any time changes.
With the z/VSE IPL commands SET ZONEDEF and SET ZONEBDY you can switch between standard and daylight local times without changing the IPL startup procedure each time. However, you have to IPL the system in order to switch to the new time zone, see the z/VSE System Control Statements for details. That book is here.
