Log import ignores date (no replies)

Cheers everyone, forum first-timer here …

I'm in the process of importing server access logs into Piwik and hit a wall there. Everything I import gets recorded with the date and time the import is running. It seems to me that the dates in those access logs are being simply ignored.

I've done this import stuff before and as far as I can remember it went well then.

I'm calling the importer like that:

python misc/log-analytics/import_logs.py --show-progress -dddddddd --url=http://mypiwik.example --idsite=<SITE_ID_HERE> --token-auth=<AUTH_TOKEN_HERE> /path/to/logfile.log

The output of that yields:

Processing your log data
------------------------

    In order for your logs to be processed by Piwik, you may need to run the following command:
     ./console core:archive --force-all-websites --force-all-periods=315576000 --force-date-last-n=1000 --url='http://mypiwik.example'

It doesn't matter if I run the suggested archiving command or not; the dates remain wrong (also double-verified by directly querying the database for those records).

A stripped down version of a tested log file looks like this (this very file generated the output above):

I poked around a bit in import_logs.py and it seems that the dates are at least correct up to the point where the whole lot is handed over to piwik.php. From there on things are out of my league to debug.

Also, all logs together result in around 150k lines and range from April to today and right now these only generate 280 visitors shown on the Dashboard. I'm aware that there's a lot of garbage in those logs and it's not a very frequented site but still this seems like very little outcome. Though I'm not sure if this won't change once the date issue is resolved.

Piwik is at version 2.14.0, PHP is 5.4.17.

If I can provide more information that might be helpful, please let me know.

Best and thanks in advance for any help
