We will be working with the Time change. We will not be doing an IPL for this time change. 
We will be doing the first time change thru command "SET TIMEZONE=". 
My question, Are there any impact for CA QuickFetch if we will do the time change without an IPL. 

We would like to do a time shift change on the fly using the SET CLOCK command. 

Is there a problem with CA QuickFetch?

There are no problems doing a manual "SET CLOCK= " to move the time ahead or behind 1 hour in regards to the CA QickFetch  product. None at all, with any batch utility or any batch processing.
