To further clarify vradeenian's post, I feel it is worth a mention that the cheat codes will only advance time if you haven't played much. It uses a 'cheat point' system, where 1 in game day = 1 cheat point. So in a full in-game year, you get 365 cheat points.
Therefore for some, it may be best to do some trading and courier missions just to pass the time. If you cheat ahead, the enemies get a boost because they will move to capture things (pirates and dominators) but the coalition doesn't have the technology needed to stop them, and they only get tech increases by you (and other rangers) killing dominators.
I typically wait until year 3 or 4 before using cheats. If you're curious, however, here are some numbers so you can pick and choose based upon your current time played in game.
In-space:
10 points - IDEAL, GUN, VERTIX, DEVICE, ARTS, MODULE, SKILL, PROGRAM, GOD, ILLNESS, STIMULANT, SHOWMAP, MEDAL, HORROR, NIGHTMAR, HELL, TECHNIC, AMMO, HATERANGERS
20 points - KLISSANCALL
30 points - BOOM
40 points - REPAIR
60 points - DROP
60 points - BOMB
90 points - NEXTRANK (this seems to work in space, as well as military bases)
250 points - SUPERHULL
300 points - HUGEMONEY, PACKING
unknown (does not specify) - HOLE
On any planet:
20 points - LOWCOSTWEAPON
30 points - RNDBASE
100 points - COOLWEAPON
On any Ranger base:
150 points - RANGERPOINTS
On any Pirate base:
150 points - PIRATES
On any Science base:
150 points - KLISSANITEM
Do not seem to work for whatever reason (worked in SR2) - BIGMONEY, 10BOMB
The only one I haven't tried yet is ARTEFACT.
