Offsets 74-75 looks like the 'local time' of the mission. It is translated into brightness by a 24 entries array of words (2 bytes) located at offset 0x6C99C. Seb76 05:39, 21 June 2008 (PDT)
So in decimal, the values are:
16,16,16,16,16,16,16,16,16,16,12, 8, 4, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
Well, yeah, those seem like the sort of values you'd expect to see in BGLOB. However, the highest value I've seen stored at MISSION[74-75] is 15... I'm not sure how you could map that range to the 24 values here. Also it's not really a "night to day to night" cycle, it just goes from dark to light.
Any chance MISSION[74-75] isn't the time, but a value derived from the time? That makes a little more sense to me.

The value is computed from offset 2 of LOC.DAT and the time of the day so I assumed it was local time. Well anyway, it is a time representation of some kind ;-) Seb76 09:59, 21 June 2008 (PDT)
Note that MISSION[76] also as a purpose here, but I didn't tinker too much with it when I first found out about it (who knows how long ago)... I think I got the impression that the type of mission would affect the BGLOB lighting scheme? - Bomb Bloke 06:03, 21 June 2008 (PDT)
I could find the following usage for offset 76:
- Power source explosion check during map creation
- Clean up of LOC.DAT and CRAFT.DAT entries after a crash recovery mission
- UFO CRASH RECOVERY/UFO GROUND ASSAULT message selection before a ground mission
- I found it set to 1 only for crash sites
Also the time is only used for mission types 0 and 1 (where dark zones use ambient level+4). Mission type 2 is hard coded to 8; and types 3,4,5 to 0x10 (for both normal and dark tiles). I could not find anything else. Seb76 09:59, 21 June 2008 (PDT)
