Extra time travelling around? This shows the fare (9)

I believe the answer is:

taximeter

I'm a little stuck... Click here to teach me more about this clue!

'around? this shows the fare' is the definition.
The definition suggests a singular noun which matches the answer.

'extra time travelling' is the wordplay.
'travelling' is an anagram indicator.
'extra'+'time'='extratime'
'extratime' with letters rearranged gives 'TAXIMETER'.

Can you help me to learn more?

(Other definitions for taximeter that I've seen before include "Where fare is displayed" , "Clock" , "What clocks the fare in a cab" , "Device in cab" .)

I've seen this clue in The Times.
