Creation Kit | Make a Quest Available after some time?

[valencia]

I'm in the last stage of finishing my follower mod and I have created a quest that basically allows to have sex with the follower once every 8 hours and to make out once every 4 hours. Now I don't want the quest to show up from the very beginning. I want it to basically show up after some time has passed with the player recruiting the follower. Say maybe like a week of service. So if you've recruited her for 1 week in-game or more then it'd kinda make sense for the quest to show up. I've tried to look at the condition functions in the creationkit page but did not see anything of relevance. 

So to simplify I want this quest to show up/become available after let's say 1 week in-game. Would appreciate it if someone can help me tackle this. Thanks.
