The time of day settings allow a more precise control of when sunrise, sunset, night, and day should start, using the game time data. This also controls the duration of the transitions for dawn and dusk. All values use a floating point number based on a twenty-four hour day: <parameter> = (0.0...23.9). This section should only be adjusted by advanced users or ENB authors as changing these value could have unexpected consequences on weather and lighting.
Enable or disable Time of Day settings.
This setting is the duration that the transition fades from night settings to sunrise settings in game hours. Basically when the sky starts to light but before the sun can be seen. The math for this is as follows: Dawn start time = SunriseTime - DawnDuration; Dawn Ends = SunriseTime. (Reference)
This setting is the time that the sunrise occurs in game.
Addition -> After this time daytime ini values will take effect. Use the DawnDuration setting to define how long sunrise values will extend going backward from SunriseTime. E.g. if SunriseTime is set to 9, with DawnDuration set to 1.5, Sunrise values will begin to take effect at 7.5 switching over to full daytime values beginning at 9. Note that this does not affect when the actual in game sun will rise or set. -TheConfidenceMan (talk) 16:46, October 20, 2014 (EDT)
This setting is the time that the middle of the day occurs in game.
This setting is the time that the sunset occurs in game.
This parameter is the duration that the transition from sunset settings fades to night settings in game hours. Basically this is the time from when the sun sets and can't be seen (SunsetTime) to the time set for NightTime.
This setting is the time that the middle of the night occurs in game.
