Daylight Saving Time - Permanent Daylight Saving Time

Permanent Daylight Saving Time

A move to "permanent daylight saving time" (staying on summer hours all year with no time shifts) is sometimes advocated, and has in fact been implemented in some jurisdictions such as Iceland, Russia, and Belarus. The United Kingdom stayed on daylight saving time from 1968 to 1971. Advocates cite the same advantages as normal DST without the problems associated with the twice yearly time shifts. However, many remain unconvinced of the benefits, citing the same problems and the relatively late sunrises, particularly in winter, that year-round DST entails.

"Permanent daylight saving time" or permanent summer time are perhaps misnomers, as the practice essentially becomes the "standard time" for the area. However, it can be considered to be a deviation from the internationally agreed timezone of the Coordinated Universal Time system.

Many jurisdictions such as Argentina, Georgia, Kazakhstan, Senegal, Sudan, Turkmenistan, and Tokelau can be considered to use a form of de facto permanent daylight saving time because they use time zones located to the east of the time zones they are geographically located in. Thus their local times are later than the time they would theoretically occur under a "pure" system, such as the nautical time system, giving the same effect as year-round DST.

    Come praise Colonus’ horses, and come praise

    The nightingale that deafens daylight there,
    If daylight ever visit where,
    Unvisited by tempest or by sun....
    William Butler Yeats (1865–1939)

    A strict observance of the written laws is doubtless one of the high virtues of a good citizen, but it is not the highest. The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation.
    Thomas Jefferson (1743–1826)

    You can feel it, in a hundred little ways year after year. It is so certain and inevitable, that the next century will be a time in which it is not simply safe, but commonplace, to be openly gay.
