[MeasureDayLength]
Measure=Calc
Formula=( MeasureSunsetMoment - MeasureSunriseMoment )

[MeasureNightLength]
Measure=Calc
Formula=( 1440 - MeasureSunsetMoment + MeasureSunriseMoment )

balala wrote:First let's clarify something: you need the time difference between [MeasureSunset] and [MeasureSunrise], or vice-versa, between [MeasureSunrise] and [MeasureSunset]? Because last one is the length of the day, while the first (what you asked for) is the length of the night.
Anyway, if you need the difference between [MeasureSunrise] and [MeasureSunset], it's a bit easier: you simply have to extract the numeric value of [MeasureSunrise], from the numeric value of [MeasureSunset] (keep in mind that [MeasureSunset] and [MeasureSunrise] are not numbers, so you can't extract them, but you can extract the [MeasureSunsetMoment] and [MeasureSunriseMoment], which are numbers):

Code: Select all

[MeasureDayLength]
Measure=Calc
Formula=( MeasureSunsetMoment - MeasureSunriseMoment )

On the other hand, if you need to get the length of the night, you have to calculate the length of day, then extract the got value from 1440 (number of minutes into a day):

Code: Select all

[MeasureNightLength]
Measure=Calc
Formula=( 1440 - MeasureSunsetMoment + MeasureSunriseMoment )

In both cases you'll get the result into minutes.

IMPORTANT: Don't forget to convert this to seconds, hours or whatever you need.

[MeasureDayLengthHour]
Measure=Calc
Formula=( Floor ( MeasureDayLength / 60 ))

[MeasureDayLengthMinute]
Measure=Calc
Formula=( MeasureDayLength % 60 )

Code: Select all

[MeasureDayLengthHour]
Measure=Calc
Formula=( Floor ( MeasureDayLength / 60 ))

[MeasureDayLengthMinute]
Measure=Calc
Formula=( MeasureDayLength % 60 )

If needed same way you can convert the [MeasureNightLength].

... and I apologize for stressing you with so many questions.

Don't worry, no stress at all. If you would stress me in worst case I wouldn't reply.
But finally have you got the skin working as intended?
