Nope. I addressed the issues I found and were reported last fall with the time change, so hopefully we are good to go.
If there are any problems, the pertinent log sections should be provided.
I should have tested this more rigorously now that the simulator exists, but I haven't had much time in the last 45 days or so to do much with wview (and I didn't even think of it).

In Europe our clocks went forward last weekend - here's the output from my syslog around that time. There was a 1-hour gap in the graphs. Maybe Mark can confirm that all is as it should be?

I don't know how else to handle the "spring forward" scenario other than the 1 hour data gap. Looks like it did what I intended it to do. It would be nice if that record at "2:00AM" stamped "1:00AM" by the VP could be displayed in the chart data instead of discarded (it is stored in the database file). I will think about that.
The real rub (to me) is in the fall - what do you do? I implemented keeping the "first" "1:00AM-2:00AM" period and discarding the "second" as I recall...
