How do I get one of these unresolved journeys, please :-) I've never
seen one yet and I sometimes interchange between the tube and DLR so
would have expected to get one when doing this. How long does it take
for an "entry" to expire, if you know what I mean?

I've had one since 3 Feb still on the card, when I took WAGN from
Liverpool Street to Walthamstow and forgot to use the platform oyster
validator.

It's hasn't blocked any gates for me though - it just shows up when I
look at the history via a ticket machine.

So - at least a fortnight!
