As I understand it, RHP runs on UMT, not GMT. The idea is that you attend to your own daylight saving changes just like altering your microwave clock.
I'd support an auto-change like the one that Windows does, but daylight saving events are so random that I suspect it's not worth the effort.
The very last thing we need is more daylight (during the hours most people are up and around) in the summer.
Hot places generally have problems with it. Australia's northern states don't run with it, so in summer the radio folk have to report 5 times instead of the usual 3.
