Best to use Uber or better still, Grab (also an app) in Malaysia. Not only will your fare be less than half the price, but your wallet will still be intact (and your dignity). Never use an ordinary taxi driver. In general, the only difference between taxi drivers in Malaysia and thieves is that the latter are usually behind bars.
Kinda like that double hour index at 7 and a quarter past 7... might add some value... but that one missing at 11 o'clock is a nogo!
When diving you need to start on the top of the hour and assume your air runs out at the 34.5 minutes so no need for a bezel.
