What is the meaning of this 将？ This 将 indicates A. 'just before' or B. 'just after' sunset? zdic.net has


将： 快要， ‘just about to' so A
将： 刚，刚刚 which I think means 'just happened', so B


那是一个夕阳将落的傍晚，.....
將 = about to = will soon

"In the evening, the moment the Sun was about to set," [...I suppose the sentence is unfinished]

edit: right, I am reminded that (slightly old-fashioned sense) 將 has the sense of 了, but that is not equivalent to 剛剛. "了" means something similar to perfect tense, but that does not necessarily happen "just before now".
