What should it look like?

So I’m working on this villain and her main thing is that she steals time from people she can steal days hours months years seconds minutes of your life or she can give it to you give you extra time to live or she can take away like I said, and this villain has a symbol calling card, but I wanna give it something different. I don’t want it to be just a clock a boring clock you know what I mean so what kind of symbol should I use? Anyone know any like ancient symbols that represent time or something like that?
