Is it normal for myMidnite to stop showing readings after timezone switch?

[pghanem]

I've always had trouble with the timezone on MyMidnite - setting to America/Vancouver doesn't actually show the time in Vancouver. So I generally ignore the time and assume that the most recent reading is recent.

But I noticed that since I tried changing the timezone for MyMidnite, I haven't got any readings come in since then. Is this a known issue, and is there a way around it?
