Abolishing clock change deemed unrealistic

The issue with changing the clock twice every year turned out to be quite a sensitive one, many people taking the opposite sides and disagreeing on what would be best. It also turned out that many EU ministers deem it unrealistic. Some of them think 2019 would be too soon to implement the changes towards ending the practice.
Many businesses would need a lot of time to prepare for a possible change, such as airlines and airports, as well as computer businesses. The situation worsens in the context of Brexit - if UK keeps daylight saving time this would create confusion between Britain and Ireland if the latter decided to follow EU regulations and abolish the practice.
