	 Cause . . . . . :   Local system time has been adjusted to use a Coordinated   
	   Universal Time offset of -360 minutes due to reason code 2. The reason codes 
	   and their meanings are as follows:                                           
	     0 - See previous messages.                                                 
	     1 - A Daylight Saving Time transition has occurred.                        
	     2 - The time zone currently used by the system value QTIMZON has changed.  

Cleanup has started.

Subject: RE: DST PTF(s) for V5R1?

Hopefully that "gradual" part is incorrect, and the system - like the rest of the non-personal computer systems in the world - merely "decodes/represents" the time differently rather than actually changing any clock.  Nowadays, most systems use the applicable UCT offset to determine what the local time is/was.

Can anyone here confirm the internal process?
