Aside from confusing the nursing staff what's the problem with leaving it always set to GMT? It is at least consistent. Airlines and such people, who have similar poblems but much worse, always maintain their times at GMT often translating it on the fly as required, surely nurses can understand this concept and do the same. You will notice that this very site clearly states that all times are GMT, but then what did it say in summer? Perhaps Huw will tell us. On my sites he time does change; NT4 is set to do it autmatically and being centralised it is easy. Untill deices ae clever enough to self-adjust or even self set we have a problem.
