I have now found a newspapper stating that at 01:00 october 1st 1916 summertime the church-clocks etc were set back one hour to show 0:00 october 1st 1916 standard time. The article also reports that some people thought the switch to standard time would take place already at 0:00 october 1st 1916 summer time, but they had to wait for another hour before the event took place. Source: The newspaper "Dagens Nyheter", ocober 1st 1916, page 7 to the upper left. /Regards Ivan Nilsson
