Is it sunrise or sunset with an offset?

Hi,

If you need to know if the current time is equal to an minute offset ( + or - ) of Sunset or Sunrise  place these scripts in the Common script.   For example, if its 40 minutes before sunrise,  you would create a resident script to run every minute.  

Code:

123

if( isSunrise(-40, 51.5072, 0.1275) == true) then   doSomething() end

example 2,  if its 30 minutes after then you would use

Code:

123

if( isSunset(30, 51.5072, 0.1275) == true) then   doSomething() end

And when you need to know if its Sunset or Sunrise then set the offset parameter to 0.

Code:

123456789101112131415161718192021222324252627282930313233343536373839404142434445

function isSunset(offset, latitude, longitude)   local sunrise, sunset = rscalc(latitude, longitude)   local now = os.date("*t")   local yr =now.year   local mth = now.month   local dy = now.day   local hr = math.floor(sunset / 60)   local minute = sunset % 60   local tm = os.time{year=yr, month=mth, day=dy, hour=hr, min=minute, sec=0}   local offsettm   if(offset >=1) then     offsettm= tm+(offset*60)   else     offsettm= tm-((offset*-1)*60)   end   local now = os.time()   if(offsettm>=(now-30) and offsettm<=(now+30))then     return true   else     return false   end end function isSunrise(offset, latitude, longitude)   local sunrise, sunset = rscalc(latitude, longitude)   local now = os.date("*t")   local yr =now.year   local mth = now.month   local dy = now.day   local hr = math.floor(sunrise / 60)   local minute = sunrise % 60   local tm = os.time{year=yr, month=mth, day=dy, hour=hr, min=minute, sec=0}   local offsettm   if(offset >=1) then     offsettm= tm+(offset*60)   else     offsettm= tm-((offset*-1)*60)   end   local now = os.time()   if(offsettm>=(now-30) and offsettm<=(now+30))then     return true   else     return false   end end

Hope this may help.

Thanks,
