Brussels has drafted legislation to end the practice of "daylight saving", which is observed by all EU countries, after the investigation indicated that voters were in favor of doing so.
The EU Commission would allow each member state to choose whether to permanently stay in their winter or summer schedules.
Although it would not enter until shortly after the United Kingdom leaves the bloc in March, its colleagues said that the United Kingdom would have to adopt it during any transition period agreed in a Brexit agreement.
The Internal Market Subcommittee of the Lords EU said that Brussels had not justified why it should make a decision on which individual countries were best placed to decide due to their own geographical and other considerations.
The EU was "beyond its reach" and did not observe the basic principle of "subsidiarity", which states that measures must be taken at the Brussels level only when absolutely necessary, since member states can not achieve the objectives.
The committee wants the House of Lords on Wednesday to agree to formally report their concerns to the EU Parliament, Council and Commission.
European countries are divided into three time zones: Greenwich Mean Time, Central and Eastern Europe.
But, to facilitate trade and communication, everyone is obliged to go back one hour to their "winter hours" the same day, the last Sunday of October, as will happen next Sunday at 2 am, and advance one hour until the summer at the end of March.
The UK government has also expressed doubts about whether the change of legislation at the EU level is justified.
The commission's chairman, Lord Whitty, said: "The European Commission's proposal to end seasonal changes in time goes beyond its scope and does not comply with the principle of subsidiarity."
Lord (Andrew) Robathan, former Conservative MP and Brexiteer, said: "This type of bureaucratic EU action that interferes with things that have nothing to do with this is the reason why many of us vote in favor.
"All of us who are part of the committee believe that in the wildest dreams of the EU, this has nothing to do with the EU, it depends on us."
Lord Robathan suspected that most people do not like the clock change twice a year.
"But that's irrelevant here, if it has anything to do with the EU and our opinion was: no, absolutely not, and most people would agree."
He added: "I am sure the EU would like us all to be in the same moment for trade, but magically we somehow exchange with India, Japan, Australia and the United States, and do not seek to synchronize with us."
The measure needs the support of all the countries of the EU and the European Parliament to become law.
The subcommittee also warned that in a Brexit without treatment, Northern Ireland might have to choose between being in tune with its neighbor Earth, Ireland or Great Britain.
The president of the European Commission, Jean-Claude Juncker, has said that millions "believe that in the future, summer time should be throughout the year, and that is what will happen."
But the committee questioned the Commission's assertion about the popularity of the change, since the 4.6 million people who responded to a consultation in Brussels were less than 1 percent of all EU citizens, and 85 percent of the answers came from only three countries.
