Better: Install "Multilingual Speaking Clock" instead (windows only I think) and set it up so it announces the time every 5 minutes through your computer speakers. It. Is. A. Mind. Game. When your brain "idles" you lose track of time. Time in the mind only exists as a comparison of one moment in the past and another moment in the present. So when you're daydreaming (mostly brain idling) time appears to fly by because there's less datapoints for your mind to use to compare. But when you're checking the time constantly time appears to go by very very slowly. It can become mentally exhausting when you do it too much though because it speeds up the mind. You become aware of every little moment. It can make you extremely productive but you really do have to take "brain idling" breaks every now and then. Also when you first start off, time will appear to fly by, it'll feel like "5 min" are flying by every 30 seconds. But after about 30 minutes your brain will stop idling so much, you'll become aware of more time points, and it'll feel like time is slowing down and you're thinking "faster". Give it a try. It's really fascinating.
