This is stupid but I'm not 100% positive. When reading a recipe the time means time till end of boil right? Like if it says Hops at 60m on a 60m boil that means as soon as it starts boiling and 1 min means right at the end?
I would start the 60 minutes at the first hop addition though. Additionaly, I would wait for the foam (or hotbreak) to subside after reaching your boil before adding the first hop addition. This will help reduce the chance for boil-overs.
The 60min addition can be boiled longer than 60min. That is the min boiling time for complete isomorisation of the alpha acids.
In addition any First Wort Hop addition is done (for all grain) when the runnings start to hit the kettle regardless of total boil time.
More complete utilzation of alpha acid isomorisation may be increased by longer boil time (and any time the hops sit above 180F or 82C) but this is also dependent on other factors.
Any addition that is less than 60 min should be done exactly in their pre-flame out count down. T-30min etc. (Really FO-X minutes)
"Whirlpool" aroma additions are done at flameout and the corrosponding time if listed means to leave in the kettle for X minutes after flameout during the whirlpool (and wort cooling if you use an immersion chiller).
beerinasippicup is on target here. Your should experience hot break within 5-10 minutes of hitting a rolling boil, and should be done 5-10 minutes afterwards, depending on the amount of protein in the wort. After the hot break, add hops and start the clock.
