Andrew, We can't use this as a workaround, but what you're suggesting is essentially what WU should be doing with the date that we provide in the query URL. WU should be doing the conversion to station localtime and returning the values for that date, relative to the station. But they seem to be returning the values for the date relative to UTC instead.
