That's all just superstition. Glorwing is a place where suddenly a city or a person can appear/disappear due to a fluctuation in the interdimensional space-time continuum (aka "rift").
The official timescale is time as it passes by definition in the Kingdom and has nothing to do with time as you and I percieve it in game.
Or short: If you're looking for logic and consistency in a world where people have wings, converse with animals or fight dragons, you're up for a great disappointment.
