On May 2018, a new law on the Belgian legal time was adopted by the Parliament, based on a recommendation from the Royal Observatory of Belgium. The legal time was, according to the law dating from 1892, the solar time of the Greenwich meridian. The new has been come into effect on Monday, september 10, 2018. Thus, today legal time in Belgium is aligned with the official world reference: the Coordinated Universal Time (UTC). The legal time in Belgium will therefore be UTC+1h in winter and UTC+2h in summer. The realisation of legal time by the time lab of the Observatory is the most precise in Belgium. The Observatory disseminates its realization of the legal time via the Network Time Protocol. The precision of the time received by the users is about a few milliseconds.
