So, if I change the time zone of the standby, then (when we switchover) if we
look at sysdate if won't be the same as the O/S time? Oracle will convert it
over to whichever time zone I set it to?

You can set the time zone of the standby server to match the primary.

We have a primary database in one time zone and a Data Guard copy in another
time zone. I know just about nothing about nls parameters, time zones, etc.
If we switch over to the stand-by copy its timestamp will be off by many
hours (records will get inserted based on the local time). When we switch
back any sorting on the timestamp fields will be out of order. Is there a
parameter I can set at the database level to keep the timestamps in order
when we switch back and forth?
