Depending on where you are located, the nights can be really long or really short.
The End Sequence at: function is extremely helpful, but some locations will have to constantly adjust this value as daylight encroachment time shifts through the seasons.
Sunrise is a value that exists in SGP in the Planning Tools.
I would like to request that there be an option to set the End Sequence at: time to be a number of minutes before Sunrise OR a fixed time. Or even simply Astronomical Twilight.
I hope you see the value in this request,
thanks,
Malcolm
