-----------------------------------------
Hi [~RenkaiGe],
I was wondering about that as well but couldn't come up with a case where that
would happen. Could you maybe given an example?
Due to the nature of mod I think we can still get away with only one mod, like
this:
{code}
public static long getWindowStartWithOffset(long timestamp, long offset, long
windowSize) {
return timestamp - (timestamp - offset + windowSize) % windowSize;
}
{code}
What do you think?

> Currently, windows are always aligned to EPOCH, which basically means days
> are aligned with GMT. This is somewhat problematic for people living in
> different timezones.
> And offset parameter would allow to adapt the window assigner to the timezone.
