Explanation
The reason as to why your script hasn't "woken up" yet is because you're either misunderstanding how classes work or you've just overlooked a part of your code (I'll assume it's the former as the answer is more informative that way).
A class is made of methods (functions) and attributes (variables). They can be used either directly (statically) or through instances. In your case you're trying to use the class Sunclock as an instance named sunfloat: sunfloat = Sunclock().
In the next line you run the suntime method using sunfloat and that sets the attributes: sunrisetime, sunsettime, curenttime, curenttimelong and date. Afterwards you just assign variables to some of those attributes.
Now, let's go to the root of the problem:
while get_sunrise > get_current or get_sunset < get_current:
get_sunset = sunfloat.sunsettime
get_sunrise = sunfloat.sunrisetime
get_current = sunfloat.currenttime
sleep(300)
What you're doing here is assigning the variables to the same attributes all the time. sunfloat.sunsettime, sunfloat.sunrisetime and sunfloat.currenttime will never change while you're in the loop, they won't get new values out of thin air - their values need to be changed.
Solution
In order to change the values of the attributes, you'll want to call the suntime method again. The method will set all the attributes to the most up-to-date values:
while get_sunrise > get_current or get_sunset < get_current:
# All the attributes get re-assigned to the most up-to-date values.
sunfloat.suntime()
get_current = sunfloat.currenttime
get_sunset = sunfloat.sunsettime
get_sunrise = sunfloat.sunrisetime
sleep(300)
