GMSThours

GMST hours refers to the unit of time used in the God of War video game series, developed by Sony Santa Monica Studio. GMST stands for "God of War (2018) Medieval Sun Time." This unit of time is based on the solar time of the medieval period, used by the architecture and astronomical phenomena in the game.

In the game, the GMST hours are displayed on sundials, hourglasses, and other methods of timekeeping that are period-specific. The GMST hours are calculated based on the game's fictional solar system, which includes the game world, Greek gods, and the Norse pantheon. The game's internal clock cycles through the GMST hours, allowing the player to gauge time in a medieval-style context.

Although GMST is used as a gameplay mechanic to showcase the passage of time in-game, the historical accuracy of the portrayed medieval timekeeping practices is debatable. However, it allows the game's world to feel immersive and historically inspired within its fictional framework. Critics have noted that this effect can help the game achieve a more realist aesthetic, immersing the player in the god-knight setting.

The game's use of GMST hours adds depth and visual narrative to the gameplay. The internal cycle of GMST hours can be seen as an ingame temporal mechanic which allows the player to have a unique insight in the in-game state of the situation.
