Terrible writing. I think it's a conflation of "as regular as clockwork" and "as sure as night turns to day".
He also describes what happened as "a daring motorcycle heist". I was expecting something worthy of a Hollywood film, not a motorcycle chain snatch attempt.
It appears that "Top" is a non-native English speaker, which is fair enough, but they should have someone proof reading everyone's work, especially when the mistakes are instantly noticeable. Although he's also apparently a "multifaceted writer". ????
