daylight savings creates useless complexity, confuses the electronic devices, travel plans, flights and many other human and post-human activities. artificial lighting, flexible working hours, remote working are all helping better day for everyone.

beyond that, following bold suggestion exist; 1) the 'second' time unit must be quicker to match average human heart rate. 2) time zones maybe abolished totally and 1 single time zone maybe used.

Using a time unit not related to the metric second would be a step back. If you use a new unit equal to half a metric second, that's too fast for normal human heart rate.

Not to mention it's highly variable; I've easily gotten my heart rate up to 192 BPM; when I was in better condition, my resting was mid-forties.

yes, not half but a bit slower. i read this from a book long time ago, but don't remember where. the guy was saying that the 'second' was a bit slower than the average heart beat rate and that made people generally unhappier because it is reflected in many things during a day.
