Time hack

Is there anyway possible for you guys to make a hack that takes time away from a mission
(example:Time left: 59:59 minutes "presses 1 on number pad" Time level 58:57minutes)
So if were hacking it wont show on rankings or anything (unless making party private does that)

You can use the "cc_change_game_message" command to bypass leaderboards. But what you are looking for does not exist, or has been patched a long time ago.

there is the command time_plus x or something like that. Though it doesn't appear to do anything.
