Query results displays different time for a field "_time" depending on filter period for the same raw data. Below two example

filter last 30

profiles.tar.gz iostat.txt

I'm experiencing the same issue, and it's baffling me.

raw data:

After the query:

I think it's a timezone issue, since the difference bw my local time and UTC is 2 hours, and that's the difference bw the raw data and the post-query _time column. Any ideas how to fix this issue? For my use-case, it works just fine if the data is represented with the correct _time column after the query, but I'd just sleep better at night if I knew how to also have correctly timed _time column in the raw data.
