I don't think this is a good idea.  If someone really relied on 'current'
for his application, substituting 'now' for it is not going to make things
better.  If it's done silently it will definitely make things worse.

If that someone replays his dump and sees "invalid date/time value
'current'" then he knows he's got something to fix -- and he has to fix
something anyway.

I hadn't thought about it, but I believe Peter is right.  Rejecting
'current' is better than silently translating it to 'now'.  We have
removed this feature and we shouldn't try to paper over the fact.
