The short answer is it started about 14 to 15 billion years ago and will end...welll...nobody knows.
The longer answer (or theory) is according to the standard cosmological model time and space, actually spacetime, began around 14 billion years ago. There is no "before" that. There may be some kind of causalty hierarchy, but not time.
As for the end of time, in more than a third of a century, the best minds in astronomy have failed to solve the mystery of what happens at the other end of time. Will the galaxies continue to fly apart forever, their glow fading until the cosmos is cold and dark? Or will the expansion slow to a halt, reverse direction and send 10 octillion (10 trillion billion) stars crashing back together in a final, apocalyptic Big Crunch, the mirror image of the universe's explosive birth? Despite decades of observations with the most powerful telescopes at their disposal, astronomers simply haven't been able to decidewhat will happen or when.

Time is a quantity that describes how fast a process takes place. a process. ;such as the motion of a mass.
If a process takes place then that is the time that the process began . If the process is oscilliatory the the time for that process is called the Period.Hence a process has a begining and an end.
Time has always existed except its manifested differently in different frame of references.
If something has always existed then it can be traced back to negative time which is back into eternity.
Human Spirit has a begining but no end..
Science speaks of a Universal collapese ,hence an end of time of the Universe.
However Science is Science and Supernatural is supernatural.
A collapse of Universal time does not necessarily means that such a beautiful structure as the Universe would end.Perhaps a change Universe is more likely to occur if you believe in Biblical account on the structure of space and mass.

Time began shortly after the Big Bang, when spacetime was created. It has no end.

We don't really understand the nature of time except that it is relative and affected by speed. My time is different than your time and both of our times as we perceive them are different from the next person and so on. We can't even be sure that time is completely non-linear so all time could be ending and beginning in a mere instant.

It began at the moment of conception.
It will end at the moment of collapse.

time began with the big bang (if there was one) and will end at the time of the big crush.otherwise time is a property of unverse's existance itself and will end with it

time started when the big bang started and ends when the universe starts to shrink itself (the big band expands the universe) ,,which means the earth , for example, will start, once the universe starts to shrink, to rotate the opposite way it rotates now and that will be the end of human time!
I guess?!

Time started when people started to count the days, months and years. It can not be known, because it happened prehistorically.

Time is on my side. It begins at birth. Ends with your last breath.
