Thanks, bnt. I don't have the 'automatic' setting, just check boxes for 'home' and 'visiting' time zones.
Bushfiva, I haven't synchronised the device as yet, and will only do so infrequently.
You say you think the device's OS gets is DST table from Outlook. Is that to say it learns the DST info, as set on my PC's OS due to its regional settings, during synch? If that's what you mean, once I synch the device with the PC the first time, the device should then learn and remember when to adjust for UK DST changes. Or have I oversimplified that?
