This is likely beyond what you care about, but note that the time values are the number of seconds since January 1, 1970 UTC **as if there were no leap seconds**. But with weather data every 15 minuts, that just means that occasionally those timestamps that differ from 900 will be 901 (or maybe in the future 899 seconds apart). And, surely your weather station doesn't have leap second support, and your computer doesn't have a network connection. But seriously, I don't know how you are dealing with time, and probably you want to have a GPS receiver and run ntpd to sync the RPI's clock, and understand how that relates to the weather station's clock. You probably also want to run the RPI in UTC, and also the weather stations, so that there is no daylight savings time confusion. weewx does not as far as I know support "operate in UTC but produce graphs/summaries in local time (meaning "today" as a 24h period, min/max, etc.)". But you are just going to process the weewx.sdb elsewhere. I would also put a USB SSD or stick in the Pi and back up the weewx.sdb to that daily, in a way that doesn't overwrite the previous backups. And a UPS (even a Pi UPS with a battery, but beware of lithium batteries below freezing). -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
