Question about 'Nighttime Operations'!!

[Jamers]

I know I posted a thread like this already, but it has like 70 views and no replies, so I thought I'd try again.

Does anyone know if 'Evening' in the lower left corner counts as night when the game mechanics are calculating things like the bonuses from Nighttime Operations, or does it only come into play when the time says 'Night' / ('Nighttime?' I forget). I know that at least one other item relies on a 'nighttime' bonus (the Dwarven Lantern Miner Helmet or whatever...+20% attack at night. Big time.)

If anyone knows, I'd much appreciate it. Thanks!!
