ENBSeriesINI - Timeofday

The TIMEOFDAY (ToD) parameters allow for precise control of when ENB effects are applied to the screen based upon Skyrim's weather system. The effect parameters themselves are delineated using dawn, sunrise, day, sunset, dusk, and night variants. The ToD parameters are derived directly from the DefaultClimate [0000015E] and DefaultSkyrim [00000812] TNAM records for Sunrise and Sunset Begin/End times in Skyrim.esm. Calculations for setting ToD parameters for any weather mod --given the plugin record values of the weather system-- follow the parameter descriptions below.

The following ToD definitions apply to the position of the Sun from the perspective of a location at lowest altitude and with East/West horizons visible without land interference (near cow tamriel 0 40). Instead of using datetime format, numeric format is expressed in floating point (0.0000...23.9999) based on the twenty-four hour day and expressed in military time. For brevity, only one decimal place is shown in the examples.

DawnDuration

DawnDuration=(0.0...23.9)

Duration from the time at which light first appears in the sky in the East until the time the sun appears in its entirety over the horizon.

SunriseTime

SunriseTime=(0.0...23.9)

The time at which the bottom arc of the sun appears on the eastern horizon.

DayTime

DayTime=(0.0...23.9)

The time at the midpoint of day (end of DuskDuration minus begin of DawnDuration).

SunsetTime

SunsetTime=(0.0...23.9)

The time at which the bottom arc of the sun reaches the western horizon.

DuskDuration

DuskDuration=(0.0...23.9)

Duration from the time at which light first begins to fade from the sky (SunsetTime) until no sunlight is detectable in the West .

NightTime

NightTime=(0.0...23.9)

The time at the midpoint of night (begin of DuskDuration minus end of DawnDuration).

Derive Correct ToD Settings for Any Weather Mod

Let the following represent the decimal values of the datetime records for Sunrise and Sunset for the weather mod:

IF ...

r₀ = Sunrise (DawnDuration) begin time

r₁ = Sunrise (DawnDuration) end time

s₀ = Sunset (DuskDuration) begin time

s₁ = Sunset (DuskDuration) end time

THEN ...

DawnDuration = (r₁ - r₀) / 2

SunriseTime = r₀ + DawnDuration

DayTime = r₁ + (s₀ - r₁) / 2

DuskDuration = (s₁ - s₀) / 2

SunsetTime = s₀ + DuskDuration

NightTime = r₀ - (24 - s₁ + r₀) / 2

Vanilla SSE

Skyrim.esm

Sunrise Begin = r₀ = 5:30:00 AM
Sunrise End = r₁ = 10:00:00 AM
Sunset Begin = s₀ = 4:00:00 PM
Sunset End = s₁ = 8:30:00 PM

[TIMEOFDAY]
DawnDuration = 2.25
SunriseTime = 7.75
DayTime = 13
SunsetTime = 18.25
DuskDuration = 2.25
NightTime = 1

 == Understanding the Durations ==
 The two ''Duration'' settings can be confusing to understand. They are essentially timers for the fade effect between two sets of parameters ([https://enbseries.enbdev.com/forum/viewtopic.php?f=2&t=1939#p27189 Reference]).
