I was having a chat with a student in a different time zone the other day.
I’m in the UK, she’s in the US.
In the UK our clocks were moved back one hour on 30th October, in the US one week later on 6th November.
Except for certain US states who do not observe daylight saving hours - Arizona for example.
We raised a question and had no answer so I thought I would put it out here.
In the UK our computers, mobile phones and other devices all automatically change their time reading according to daylight saving or standard time.
How does that work in countries such as the US?
People in Massachusetts and Arizona and California all buy computers and electronic devices. Yet only in the first and last of those states do the clocks alter in spring and autumn.
How do the computers know whether to change or not?
I was told there is a groundswell of opinion in many US states to end daylight saving. If that happened, would there be another panic situation fearing that all computers would cease to function, much like the millennium bug caused panic that the world would suddenly stop when the year 2000 came?
