When you have several identical animated sprites in your scene, they all start at the same frame.
I wanted to have them start at random frames
I googled a lot about this subject without finding any working and clever solution.

So here is the simple solution I found:

Animator anim = GetComponent<Animator>();
AnimatorStateInfo state = anim.GetCurrentAnimatorStateInfo(0);//could replace 0 by any other animation layer index
anim.Play(state.fullPathHash, -1, Random.Range(0f, 1f));

Here is a downloadable script that you can just drop on an animated GameObject:
RandomStartTime.cs

I hope this will be useful to someone else.

Thanks for that. I remember trying to do that once but I don't remember how I solved it.

THANK YOU! This works like a charm!

Semi-related thing that I had to do yesterday which may be obvious to some, but for reference in case it helps anybody:

I already had a working state machine (mecanim) integrated with the code and everything that I didn't want to modify, but then changes were made to design by the artist, who wanted to play a different animation in one of the states depending on some variable. Solution was to replace the old state (just an animation clip) with a blend tree, so that I could retain that one state, with the same transition arrows, but have it select one of five different animations depending on the blend value (which I modified to go between whole integers instead of 0-1), which was filled in by the variable in question.
