I can never get Reports to work when I specify a period between two dates.
If I enter the two dates, it just produces a blank report.
If I leave the period from/to fields empty it does produces a report - but for the entire period the router has been gathering data.
I had thought this might be due to erroneous dates in the database, related to NTP because I have been using remote NTP servers. For instance if the device boots up after a power outage and is active before the gateway, and someone logs on it might not be able to synch the clock in time and record a bad start time (I see sessions with year 1970 when this happens).
Can anyone point to possible causes, thanks.
