The technical explanation is much appreciated - I'd gathered (more or 
less) as much from my searching and reading the leap second Wiki.

So, the situation is that, basically, leap seconds are "fudged" to use 
the technical term!

I asked the question with a view to having accurate TIMESTAMP 
differences - i.e. to the second. However, since everyone is fudging 
(incl. AFAICS Oracle and SQL Server), this means that accepting the 
status quo will just make my inaccuracies will be the same as everyone 
else's, ergo I'm golden!

At least that's one issue that I can safely ignore - I didn't fancy 
implementing this on my own.

Thanks again and rgs,


E!
