In 1992, the European Commission engaged DSC to examine the costs imposed by the then prevailing difference in the end of summer(daylight saving)time, whereby Ireland and the United Kingdom changed to wintertime at the end of October, a month later than the rest of Western Europe. The study, carried out in collaboration with ACT Consultants, identified substantial costs, but concluded that these were small relative to the disbenefits of a longer summertime period in the other countries. This finding was taken into account in the Commission's recommendation that the end of summertime should be harmonised at the end of October.

In 2012 DSC prepared a report for the Department for Business Innovation and Skills to look at the scope, quality and robustness of available evidence that could be used to assess or monitor the potential effects of a policy to move the clock forward the year round in the United Kingdom.
