Hmm don't really have a stopwatch, but I'll try to figure something out, sure. But yeah, 30 seconds sounds about right. Actually now that I think of it, it seems that the 5 time unit spell I was testing lasted just under 10 seconds, more like 9 maybe. But again, I was just counting out my best estimation of a second.
Would this possibly mean that the day/night cycle might be faster or slower depending on your settings?
hmmm...this is bad then, because my level 1 bless lasts only "up to" 19 seconds, and that means i am only getting 2/3 of the full potential of any spell that "lasts x time units".
