How long to cook syrup for Baklava?

I want to make Baklava, but I do not know how long to cook the syrup for.

Some websites say 4-5 minutes, some say 20 minutes, and I am clueless…

I am using an 8×8 pan, 7 oz of white sugar and 7 oz of water.

Is there a specific temperature I should cook it to?

Edit:

To avoid confusion – I am not looking for a simple syrup recipe, like the ones used to flavor drinks or keep cakes moist.
I need a "light syrup", used for oriental sweets (as I’ve read), and most of the recipes call for "5 minutes of gentle boiling", so that is my best bet so far.
