ok - it's a known issue because you are not running a realtime clock on your pi. You can add a RTC module for a few dollars, or live with the annoyance (at this time) since weewx is running ok.
You could probably try to crutch it with a cron job that restarts weewx 10 minutes after a reboot (untested) if it bothers you that much, but you still need quality system time before weewx will come up reliably. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
