It is a problem peculiar to countries in the higher latitudes.
Ireland experimented with permanent summertime, from 1968 to 1971. Teachers complained that children had to leave for school in the dark on winter mornings, frequently in bad weather. It was also much colder before daylight. It was difficult to begin a day’s work in darkness on building sites. Postmen, council workers and deliverymen suffered. Changing of the clocks resumed in 1972.
Some countries are thinking about implementing ‘single double summertime’, (SDST) to move their clocks two hours ahead of Greenwich mean time (GMT) in the summer, and one hour ahead in the winter.
Ireland should set its national clock from an Irish perspective. Our best might be to split the difference of one hour between summer time and winter time. True Dublin time is 25 minutes behind GMT.
Therefore, let Irish summer time be 30 minutes ahead of GMT all year round.
Any decision to change the clocks should be a political one, based on the advantages and disadvantages of maintaining the status quo.
