How to get Time difference (in minutes) between Sunset and Dusk

[Bluesbirdy 3]

Hi Y'all,

 

I spend hours and hours looking for an answer (if any ...) to my self induced problem.

 

I use the 'Sun_calc' device for displaying sunset, dusk, sunrise etc. etc. in my HC3.

Works like charm.

I created Global Variables and they are correctly displaying e.g. "17:05" and "17:35" for sunset and dusk.

 

But I would like to use the time difference between those values ( i.e. 30 in this case), so I can use that value somewhere else.

I like to put that value into another Global Variable, so I can use it in any scene I want.

 

I haven't the faintest idea how I can convert those string values into 'minutes' so I can do math on them.

 

Anybody?

 

Tnx in advance.

Wow, this works! Thank you.

Sorry I couldn't find this kind of basic information anywhere.

 

One more thing and then I never bother you again !??

When I try to put the value:    (hm2sec(x2) - hm2sec(x1)) / 60    into my Global Variable, I get the message "Assertion failed: Expected string".

Can you explain to me why I cannot enter the result of that equation as a number into the variable?

 

I do not understand that, because I can enter a random number manually to the variable without any problem.

Maybe I begin to see the 'light' when this becomes more clear

 

Tnx.

Hello @Bluesbirdy

Save global variables in string!
Tostring (number) and tonumber (text) are responsible for the conversion.
Try that out

Hi FBerges, I got confused because the number 30.0 appeared as '30.0' in the Global Variable.

When I enter 30 (manually) as value into my Global Variable, the number 30 appears without the two single quotation marks.

That's why I thought is was not correct.

 

But, all is clear and working, thank you.

 

Guten Nacht.
