Wonder who has also spotted such incidents before.
This evening I was greeted by this display.
Station entrance: Dhoby Ghaut Arr, 7 mins. HarbourFront: 4
mins
Concourse level: Dhoby Ghaut 4 mins. HarbourFront Arr, 7
mins
Platform: Dhoby Ghaut Arr. HarbourFront: 2 mins (This one
nothing to say, takes time to walk down).
The platform display for Dhoby Ghaut is faulty as it still
displays Dhoby Ghaut even though there's no train in station

Spotted one-north station concourse screen using CCL open
house display setting

I realised the train door dwell time sot sot one. Kent Ridge's
is shorter than one-north.
