Added execution time in discord.js bot console

I created a discord.js bot that works all the time. In the terminal where the bot is running I would like the running time of the bot since it started up to be displayed below “I am connected !”.

Here is part of my console code :

client.on('ready', () => {
      console.log('I am connected !');

Do you have any ideas ?

Thank you in advance for your help.
