They are all the same (except for the change from "-" to "^" due to
8.4), and correct, e.g.:

(LNM$SYSTEM_TABLE)
  "SYS$TIMEZONE_DAYLIGHT_SAVING" = "0"
  "SYS$TIMEZONE_DIFFERENTIAL" = "3600"
  "SYS$TIMEZONE_NAME" = "CET"
  "SYS$TIMEZONE_RULE" = "CET-1CEST-2,M3.5.0/02,M10.4.0/03"

Note that the satellite is NOT booting from the upgraded node.

See above; the same.

Right now it is 14:36; not sure what you mean.

As I said, I noticed this after the upgrade.  I'm almost 100% certain it 
wasn't there before.

Note that I upgraded a week ago, and DST starts in about 24 hours here.

I've never run nptupdate.

When a satellite boots, where does it get the time from?

It COULD be that the upgraded note is providing the MOP download.
