I have a basic understanding of the law of conservation of energy. It pretty much says that something can't come from nothing.
Good.
​
If you think back to the very beginning of things wouldn't there be a time where nothing existed?
Not if you think out box, sans bible redux.
​
If there was a time when nothing existed then how does anything exist today?
​
There never was such a time.
​
Doesn't the "existence" of "things" today violate the law of conservation of energy, because in the beginning nothing existed?
​
No.

It seems to imply that mass/energy is required for time to exist. Could someone explain it or give me some links?
​
Time is not a real and perceptible object. It is infered by presence of change/motion. Even biological change. In an absolute stasis, time would not be observed.
​
Space too is an infered object. An observer needs the presence of material objects to be concious of space.
​
Suppose you are the only entity in the otherwise a completely empty universe. You would even know if there is a space or time.
