I would say that "That clock is ticking" is not an idiom. 

"Time is running out" is an idiom I would say, because running has no relation to "time". So "running" is used in a metaphorical way, whereas "ticking" is not used in a metaphorical way. 

Curious what others have to say about it. 

So would "The clock is ticking" just be an expression or something else?

Hello! Really quick question.

Are "The clock is ticking" and "Time is running out" idioms?
