Way to speed up time inside Docker?

Suppose I have an app that does something on a timer every second. Is there a way to make the timer tick 10 times a second using Docker? So the app appears to run faster to anyone outside the Docker container.

@David Maze's answer is great, that's exactly why I asked for more details about the timer :)

Just to add some ideas, I think there could be 2 ways to solve the problem:

  1. Include logic in the app itself to execute the required instructions in the required time interval;
  2. Build a second app to orchestrate the execution of the logical app, according to the set time interval.

Docker containers share the host's kernel and clock. Time is the same inside and outside the container. If a privileged container changes the time, it will change the time for the entire system. You can't make the clock in a container run at a different speed or otherwise show a different time from the host (up to time zones).
