Duplicated pulse bug (DST related?)

Ok something weird and kind of dumb just happened to me last night. For reference, I’m fully up to date; running whatpulse 2.2.1, using win7.
So I was going about my business and suddenly I see this error dialog for whatpulse pop up saying something to the effect of “Pulse throttled; your last pulse was 0 seconds ago.” So I’m like “Wtf, how could this happen given my autopulse settings?” I check my client window, and I see that somehow Whatpulse seemed to have pulse after 1 hour uptime as I configured but it didn’t reset the local unpulsed statistics. o.O
After restarting the client (because before doing this it would let me pulse due to activity throttle) I unwittingly tried pulsing again and it worked. Much to my dismay however, I discovered when looking at the website that I effectively made a duplicate pulse. Or so I thought…now I realise that it seems like it has something to do with DST.
These are the two pulses

http://whatpulse.org/stats/pulse/104600837/

Notice how close in time they appear to be. But really, that’s only because of DST ending I now believe.

Not sure how this can be called a bug, as it did exactly what you configured it to - only you got an extra hour last night.

Well, should it not run off UTC or something internally? I mean, the fact that the clocks “went back an hour” meant that it wrongly believed throttling was appropriate.
