Consistent Timeflow and Custom Timescale is an addon for the game Red Dead Redemption. 

Consistent Timeflow and Custom Timescale mod allows you to set the time of day as either daytime or nighttime, and also allows you to set the length of the day as either longer or shorter than the vanilla version of the game. 

However, if the player is using another mod to change day length, this mod will not work with it, and the player will not be able to change the settings of Consistent Timeflow and Custom Timescale.
