Since my weather station (Davis Vantage Pro) moved to British Summer Time,
BST on the 27th March '05 when the station uploads records to the Weather
Underground website I get duplicate records on their website. I had been
uploading for nearly five months (I started after BST ended!) without any
problems and nothing ever changed at my end (but for the time!)

I've tried resetting the date and time to synchronize the time on the
station with the software and PC; disabling the 'Auto-Detect' feature and
manually enabling daylight saving but have never been able to solve the
problem.

My station ID is 'IEDINBUR1' and I don't think I'm alone with the problem.
The only way I can get around this is to upload once a day to minimise the
spureous records.

The information I get in my event log is, e.g. "Duplicate entry
'IEDINBUR1-2005-04-02 13:49:45' for key 1".

Does anyone have any suggestions how to resolve - Davis and Weather
Underground didn't offer any solutions.

Look forward to your suggestions.
