Time is time, no matter where we are in the world. However, it seems like whenever we wait for a friend to get ready, five minutes can seem like a whole day. And meanwhile, a really interesting two﹣hour movie may feel like it only lasted a few minutes. So, how is it that time doesn't always seem to follow the same rules? What actually affects( 影响)our feeling of time?

According to a new study published in the journal Nature in August, the differences in how we sense time come from a"clock? inside our brain. However, the brains clock, controlled by a network of brain cells, gets its sense of time from our experiences and memories, reported Medical News Today. So, unlike regular clocks, our brain forms a " subjective(主观的) time coming from the ongoing flow of experience," Edvard Moser, director of the Kavli Institute based at the Norwegian University of Science and Technology, explained in Neuroscience News.

To examine the activity of this network, a team of scientists at the Kavli Institute studied the brain activity of rats for several hours, during which time the rats were required to complete a series of activities. According to Neuroscience News, it was found that when the rats carried out any repetitive(重复的)activities, the brain network became more precise. It matched the actual time of day. On the other hand, when they took part in any exciting experiences the brain network didn't rely on real time markers. This led to time passing unconsciously(无意识地).

According to Moser, to speed up or slow down the brain's clock depends on whether the brain simply judges time based on experiences it processes(加工). "If we change what we are doing, we also change our experience of time, he told the Norwegian Broadcasting Corporation. " It's not about clock time but about our subjective feeling of time.
