[SOLVED] Settings in TIMER?
- 
 How do I set the timer to 90 mins before sunset? The text says 'HH : mm : ss' but there are only 2 boxes to fill in, not three as expected and I am unsure as to if these boxes are to add or subtract time from sunset at my location anyway? UPDATE - I figured it out. IF you select before sunset then the boxes are hours and minutes before the sunset time. I will be testing this out today so if it is any different I will let you know!

 @skywatch It is working well and as expected!
