Yes, something the court has to take account of is the passage of time since the event and it is entirely reasonable for your memory to be an issue that has to be taken into account. You may be closely questioned on this and to be honest you will have to be frank on how reliable at this stage you think your memory is. You gave evidence in the past nearer the event, and if you still think that evidence was true the fact that you now no longer have the same relationship with it is not that relevant, I should have thought. It is what you said then that is probably most significant, even if now your memory of those events, or even if now what you then thought they were, is rather vague.
Nothing to worry about legally, although don't quote me if you are sent off for hard labor!
