In that case it would always display 1 minute from 1 minute 30
seconds. But it should display 2 minutes from 2 minutes 30 seconds to
1 minute 30 seconds. Did the original post imply that 2 minutes is
displayed for longer than this?

That's what I meant. For example, the 2 minutes time is displayed for 1 min,
20 seconds. The worse example I've seen of stuck minutes has been on the
Circle line where a minute can be anywhere up to 2 minutes in real time.

Peter's reply explained a lot.
