All you need here is `robot.brain.happyHourStart = newHappyHour`.

Also, I'd consider wrapping all the data that you need for your script in a single object; i.e.

```coffee
robot.brain.happyHour ?= {} # make sure our storage object exists
robot.brain.happyHour.start = ...
robot.brain.happyHour.end = ...
```

So that if you ever needed to move/change where your data is stored, you can do it all at once.
