Summer Time shifts happen at 2am (or thereabouts) local, so that there  
are windows when the delta between adjacent timezones, even those  
following equivalent summer time rules, change.  The world still turns.

When the leap second is applied is irrelevant for 24x7 operations.  So  
the issue you raise only affects daytime only shops.  What stops leap  
seconds being applied at local 2am?    Are there really non 24x7  
processes where a 1s offset from UTC for less than one day, with the  
clock remaining monotonic, are an issue?  People who get their leap  
seconds by slewing the clock to match NTP or a local reference don't  
care, only people who step their clock in response to a lead second  
announcement, so who are these people?
