Many US states change their clocks twice a year but there are strong views about the policy and whether it should continue.
Donald Trump wants to scrap daylight saving time across the US, which the president-elect claims will save money.
Posting on his social media site, Truth Social, he said he would try to end the practice of changing clocks each spring and autumn.
“The Republican Party will use its best efforts to eliminate Daylight Saving Time (DST), which has a small but strong constituency, but shouldn’t!”
“Daylight Saving Time is inconvenient, and very costly to our Nation,” Mr Trump added.
Many US states put clocks forward one hour in March and back an hour in November to maximise daylight during the summer months.
There has been a long-running debate about the policy, not only in America but elsewhere including the UK.
Time to stop messing with the clocks?
DST was first introduced in Germany as a measure during the First World War due to wartime coal shortages and air-raid blackouts.
The UK also adopted the changes soon after and while the US did briefly dabble in DST, it was only for seven months and was not reintroduced until 1942 during the Second World War.
DST has been in place in nearly all US states since the 1960s but some do not change their clocks at all, such as Arizona and Hawaii.
Supporters of remaining on DST argue it leads to brighter afternoons and evenings and more economic activity during the winter months.
