This month many countries change their clocks to summer time (Daylight Saving Time - DST). One of the first countries will be the USA (most of the US). They change to DST on March 13, 2016.
A year ago I had a blog entry for the time change, that I want to re-post today:
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.
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.
