I am a bit early, but may be this blog entry has value for your planning. It's a reminder as every year.
Many countries change to Daylight Saving Time (DST) in March. E.g. Canada and the USA will change on March 12, 2017 (most states), Germany on March 26.
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.
Therefore I recommend to IPL the z/VSE system for any time changes.
