OK. More info. I checked Pat O'Brien's website and also Juan Antonio Mosquera's website. Neither shows the date offset that my website shows. So, It looks like I've got a problem with my implementation or my database. But, since the NOAA reports for monthly min and max seem to be correct, that argues, I think, that the database is ok.
Where should I look? I considered time zone offsets, but Pat and I are in the same time zone and his website doesn't exhibit the issue. Is it in the calculation of daily min and max? Is there a way to clear them and recalculate/store them in the database? Best, Phil On Monday, September 24, 2018 at 10:24:30 PM UTC-4, Philip Kutzenco wrote: > > Ah, yes. Gary is correct.
