In reply to MM0FMF:
I’m sure you can! But as an engineer the fact that there are
pitfalls to get around only makes the task more challenging and
therefore worth doing.
I think the pitfalls are human interface problems rather than technical issues.
Well the entries in the alert database would be in UTC, it’s the
displayed time that gets fondled to local time by applying the user’s
Is that the user’s home local time or the local time at the activation site? Not the same thing.
A time zone is more than just an offset; you need to specify the daylight savings time rules as well. So everybody needs to be able to select the correct set of conversion rules. And the rules have to be kept up to date.
What happens when the UK Parliament decides that we will go to UTC+1 in winter and Scotland decides to opt out?
It could all be done, but I fear it would add more confusion than there is now. Amateur radio has always worked on the basis of using a common time reference world wide. It’s not a difficult concept and we of all people should be well used to it.
Given that the Internet now means that we can regularly interact in real time with people anywhere in the world, I think it’s about time that we forgot about local time zones entirely. Set all the world’s clocks to UTC, that’s what I say!
