archive log mixing UTC and local timezone

[valmiRe]

Hi all, I was wondering if there is a problem with the archive process mixing UTC and local timezone.
My timezone is UTC+1, the process logs in UTC, but the last line below is confusing, it mixes UTC (16:05:19) and local timezone (17:20:01)

logs extract of 2 last core:archive runs :

tracking data found for website id 1 (between 2016-01-28 16:05:19 and 2016-01-28 17:20:01)

Here it is supposed to check whether there were visits since midnight or since the last archive.

I presume your last archive was at 16:05:19 and the cron executed again at 16:20:01. The query always to detect if there were visits always adds one hour and makes it 17:20:01. I believe I added the + 1 hour or refactored it but to be honest I don't remember why. There might be eg a feature allowing you to import visitors up to one hour in the "future" and this way it covers it. Anyway, the +1 hour shouldn't "hurt" nor should it cause any problems re performance and data should be still correct.
