Is there a way to debug now/w and now/w+1w vars?

Hello! I have a filter query to determine tasks which somehow appear on the current week:

(startDate < now/w && endDate > now/w+1w) || (startDate > now/w && startDate < now/w+1w) || (endDate > now/w && endDate < now/w+1w)

But I have a problem on borders of a week. E.g. if I have a task which starts at next monday 00:00:00 and current day is Thursday, somehow it got filtered and I see it in my current week view

Earlier I had the same problem, but my time zone setting on server was set with default value. After setting it to GMT+3 it seems that a week starts at 07:00 AM Monday instead of 00:00:00
