Good idea.  October does have 5 Sundays this year, and I noticed this 
yesterday (Sunday).

  "SYS$TIMEZONE_DAYLIGHT_SAVING" = "1"
  "SYS$TIMEZONE_DIFFERENTIAL" = "7200"
  "SYS$TIMEZONE_NAME" = "CEST"
  "SYS$TIMEZONE_RULE" = "CET-1CEST-2,M3.4.0/02,M10.5.0/03"

This is 7.3-2.  (I would have upgraded all nodes to 8.4 but don't want 
to risk DECwindows not starting.)  The two non-satellite 7.3-2 nodes, 
including the bootserver of the satellite, have the same rules (but they 
haven't booted in almost a year).

8.4 shows

  "SYS$TIMEZONE_DAYLIGHT_SAVING" = "1"
  "SYS$TIMEZONE_DIFFERENTIAL" = "7200"
  "SYS$TIMEZONE_NAME" = "CEST"
  "SYS$TIMEZONE_RULE" = "CET^1CEST^2,M3.4.0/02,M10.5.0/03"

Apart from "-" being replaced by "^", they seem to be the same.
