Thanks, Gary! This was all very helpful. In addition to what you've described across the east vs west of GMT, I get similar behavior if I am within X hours of my local UTC offset when querying my own station. Last night as soon as localtime rolled over midnight, the queries for the previous day were correct. --Leon > > Gary -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
