Need some variables edited for a day/night cycle script

Basically I need these variables edited for a small script, I’ve been at it for a while and can’t put my finger on it.

[lua]// variables.
local DAY_LENGTH = 120 * 24; // 24 hours
local DAY_START = 5 * 120; // 5:00am
local DAY_END = 18.5 * 120; // 6:30pm
local DAWN = ( DAY_LENGTH / 4 );
local DAWN_START = DAWN - 244;
local DAWN_END = DAWN + 244;
local NOON = DAY_LENGTH / 2;
local DUSK = DAWN * 3;
local DUSK_START = DUSK - 244;
local DUSK_END = DUSK + 244;
local LIGHT_LOW = string.byte( ‘a’ );
local LIGHT_HIGH = string.byte( ‘z’ );

[/lua]

I’d like an entire cycle to last 6 hours.

Thank you

You don’t need to edit those variables, you need to set the console variable, daytime_speed to something, not edit the other values. If I remember right an old thread about this said setting daytime_speed to 60 is a real day, 24 hours, and 6 hours is a quarter of a day try setting it to 15 and see how long your day takes.
