Legal Time: The Authority of the State

Who tells the clock what time it is? While science provides the measurement of time, it is the law that provides the **Official Time**. This is a power reserved for sovereign states.

The Standard Time Act

In the United States, the official time is governed by the **Standard Time Act of 1918**. This law gives the federal government the power to define the boundaries of time zones and to establish when Daylight Saving Time (DST) begins and ends. While states can't create their own time zones, they can choose whether or not to observe DST (as Hawaii and Arizona have done).

International Law and the ITU

Globally, nations coordinate their time through the **International Telecommunication Union (ITU)** and the **Bureau International des Poids et Mesures (BIPM)**. However, these are advisory bodies. If a nation like North Korea or Venezuela decides to shift their time zone by 30 minutes for political reasons, they have the legal right to do so under their own sovereignty.

The Maritime Clock

On the high seas, time is governed by **Maritime Law**. Ships typically use "Nautical Time," dividing the ocean into 15-degree longitudinal slices. However, the captain of a ship has the ultimate legal authority to set the "Ship's Clock" to whatever time is most convenient for navigation and crew safety.

Conclusion

Time is as much a political construct as a physical one. On the Epoch Clock, we provide the reference of the Unix Epoch, which is the "legal time" of the digital age, regardless of what any individual government says.
