Mathematically define the relationship between the conservation of energy and time invariance.

I don't know what I'm reading. It has something (?) to do with Noether's proof for time symmetry in Langrangian mechanics.

Alright, so I did find http://en.wikipedia.org/wiki/Noether%27s_theorem#Example_1:_Conservation_of_energy . Apparently, I need to know about action first. XD Darn, why do I keep getting these questions?
