in one's sweet time: o que significa?

If you're not living under a rock or maybe isolated from the rest of the world you must've noticed the terror of a new virus outbreak. It's hard to escape from the news about coronavirus because it's everywhere on TV, radio and social media. And speaking of social media, I just saw a recent post by dua lipa urging fans to take care of themselves.

She also takes the chance to criticize the government because according to her they have taken their own sweet time to tell people what they should be doing to protect each other. And if you scam through the expression one's own sweet time for the first time  you might easily misunderstand it. That's why I decided to bring the expression to my blog.

If you do something in your own sweet time you do it in your own preferred pace, without consideration for how it will affect others. So getting back to dua lipa's post, what she is worried about is that if the government doesn't take matters seriously on time, the virus will spread more.
