Updating daylight time on windows 2016
These updates reflect any changes in transition rules for affected time zones.
Question: I want to understand how Oracle does daylight savings time (DST).
When the transition rules for Daylight Savings Time (DST) change, existing data, particularly that with the datatype of TIMESTAMP WITH TIME ZONE, may be affected.
The way Oracle stored this data makes it susceptible.
By moving clocks forward, people could take advantage of the extra evening daylight rather than wasting energy on lighting.
And this year, DST begins on March 12 and ends on Nov. Benjamin Franklin takes the honor (or the blame, depending on your view of the time changes) for coming up with the idea to reset clocks in the summer months as a way to conserve energy, according to David Prerau, author of "Seize the Daylight: The Curious and Contentious Story of Daylight Saving Time" (Thunder's Mouth Press, 2005).If you’re obsessed with seeing the exact atomic clock time on your computer no matter what, you may want to set up synchronization with a remote server.
