Hello Hussam, You could also say in some occasions ( depending on the context): - " It's time " : It's time to go. It's time we go home.

hi, the most common and practical of course is "time is up" (sometimes pronounced as 'time's up!). I agree with Mister Wright that 'the time has ended' or 'the time is over' will depend on what topic you are talking about: ex. "the time has ended for humankind." - it depicts the end of the world. (in this case, you can't replace 'the time has ended' to 'time is up!') other relevant sentence would be: "the time has come to an end." :)

Oral English, time is up, pronounce TIMZ_UP

Hussam: I'd like to see the context to give a better answer, but I'd say the only one that works well is: "time is up". I suppose you could say, "the time has ended", but it depends on what you are talking about.
