Since 1893-03-29 Danish standard time has been defined as "the mean solar time for the 15th degree of longitude east of Greenwich" (machine translated of the offical law). With the introduction of UTC we didn't update that law, but we did start using UTC+1 as standard time in practice. So for around 50 years maybe only astronomers have been following the law. The Minister of Transportation has now proposed a bill to update the law to define Danish standard time as UTC+1 to keep up with reality. At the first reading all political parties expressed their support and jokingly noted that "it was about time". The updated law is expected to take effect on 2023-03-26.
