[SOLVED] Settings in TIMER?

[skywatch]

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!
