For my application on FPC Sparta , DateTime returns the day and date for the previous day, one day earlier than it should be. At least for my testing here in GMT-5 (New York Area). However, the weather retrieved is correct. The weather conditions retrieved are for tomorrow, which is correct, but the date and weekday info are for day(0), which in this case would be the current day. I have programmed a work around in my .pl file awaiting the fix in v0.3.1.
