Day/night loop, ...is melting my brain Options

[Dudeinabox]

I created a day/night loop for one of my maps, now either i'm too impatient to wait for it to happen, or i've done something wrong and need help (I did wait for about an hour and didn't seem to change.)

Anyway here's the set up:

Original Ambience value: 0.634 etc, Locals: get dark (Clear) and Get light (set)

Triggers:
Name - Daybreak, set to reapeating
Events - 1: Elapsed time - 1500, 2: Local set - Get light
Actions - 1: Set ambient step - 1004634557, 2: Set ambient rate - 1063785690, 3: Set ambient light - 90, 4: local clear - Get light, 5: local set - get dark

Name - Nightfall, set to repeating
Events - 1: Elapsed time - 1750, 2: local set - get dark
Actions - 1: Set ambient step - 1004634557, 2: Set ambient rate - 1063785690, 3: set ambient light 63, 4: local clear - get dark, 5: local set - get light

Does anything seem wrong there? I did just plug random numbers into the step and rates so i'm guessing that's where the problem will be but all forms of help is much appreciated.

cheers,
