0 visits in last last52 days, 0 visits today

This also looks weird. It took 43s to calculate 52 empty days? I guess I've seen such issues recently - archiving incorrectly outputs 0 visits.

FYI: Archiving an empty day taking about 1s sounds realistic

Got valid numbers:

It works for me as well and can't reproduce it either. Also had a look at the code which looks good. Maybe your system had some kind of problems writing the log line. I'd recommend to try to reproduce with latest version from master and if you can reproduce it maybe quickly debug it?

I just again re-started the archiving script and got a weird result on first website:

INFO [2015-08-31 07:03:11] Archived website id = 1, period = day, 2 segments, 0 visits in last last52 days, 0 visits today, Time elapsed: 2.810s

I would expect 07:03:11 - 07:03:06 = 4 or 5 seconds, got: Time elapsed: 2.810s - the counter being used is the wrong one

There are three different timers. Total timer, Website timer and I'd name it "period timer". It took 2.8 seconds to archive that period and it should be correct, there were possibly 1-2 seconds spent on general website related archiving stuff but one cannot really assign it to a special period. I know it's weird that it says - pre-processing all visits at 03:06 and it looks like the timer is initiated too late there. I will issue a PR that might fix it but I'm not sure. In the meantime I prepared and threw away 3 replies to this... the code is a mess and it's not really possible to understand all this.

As PR was merged we can close this as well?
