This actually is not true. Humans may be the only species that has built physical devices for keeping track of time, but many other organisms do so in their own fashion. If they do not keep track of time, they fucking die. Birds and butterflies must migrate, locusts must know when to rise up out of their dormant state, mammals must know when to hibernate, trees must know when to drop their leaves, etc. Even humans have a circadian rhythm that allows them to function properly and keep a schedule without an actual clock. The very last part may be true, or may not, be since we do not know what other creatures are thinking.
And the worst part about this is that we can't fix this problem whiteout creating other problems. So now we have go on with our lives knowing this and feeling helpless
Not really. I don't think it's quite as dire as this book is saying it to be. Yes it's nerve racking and a little scary to know you're running out of time, but it usually motivates people to do more and achieve greater things and if they don't, it's usually because they didn't care enough. All organisms know they're going to run out of time because they all know they're going to die eventually. The only reason it's terrifying to us is because we want to do so much in our lives while other organisms' primary reason to live is to reproduce. They don't have advanced societies like ours that tell us we must do something, must make some kind of footprint before we are out of time, so essentially, the paralyzingly fear isn't of running of time, but of disappointing ourselves and others with how little we've done in our lives.
Well actually other animals use the position and movement of the sun, and many dogs (domestic that is) will learn a schedule through repetition.
All species have automatic body clocks too, they're not that accurate but they're still a thing.
