rectifying error on naturalisation certificate

On my approval letter, the home office gave details on what would be printed on the citizenship certificate and they mis spelled my place of birth. However they advise to book the ceremony and then send them the certificate for correction. does anyone have an idea how long does that take? i am hopeing it is quick

i recieved my certificate yesterday and send it to the UKBA for correction of details, does anyone know how long they take for this? anyone had similar experience? please share ur views
