Get Lollipop clock functionality back in marshmallow?

[AC Question]

My LG V10 was recently replaced after getting stuck in a boot loop. When I received my replacement, it had marshmallow loaded. I was using lollipop and am noticing the differences now. Is there a way to Get the Lollipop clock functionality back? The alarm on lock screen and ability to DoubleClick the clock in the notification bar to acess the clock app was exremely convenient. Is there any way to bring this functionality back or am I screwed? Thanks.
