There was a more significant effort to decimalise time (and the calendar to some extent) after the French Revolution, along with introducing the metric system everywhere. People hated it and they eventually switched back. A bit of related trivia is that France only accepted the Greenwich Meridian on maps/charts on the condition that the international meridian conference (of 1884) also concluded that the convened nations also resolved that decimal time was a good idea and they should work towards it.
