Ah! followed by Eek! Now I see the light. It's very bright and painful.

What I can see is that expressing this accurately and unambiguously is 
going to be _difficult_. How do you know accurately the point just 
before a transaction was completed. There must be a good subset of 
candidates that can be labelled.

Is there anyway to label/name a transaction that can be kept somewhere ? 
Like "begin transaction 'bigtrasacation26';" - is there any allowance in 
the SQL standards for naming trasactions ?

PS I have fixed my system clock - apologies to my earlier reply being a 
month ahead.
