That depends. What has changed? Time is supposedly constant, but we measure it intuitively through present-past=difference, or time. So that means future-present=difference, or time. But what about before the Big Bang, nothing could change. When did it start? If we meditate alone in silence can you estimate wether it's been 45 minutes or 2 hours? Once you smoke dmt you perceive infinite changes, and you experience thousands of years. Did you time travel?! What if we all smoked dmt at the same time? What is "at the same time" ? We all must view different changes and experience our own fluid sense of time. If we are truly aware we realize a clock is a fucking liar.
