Hi,
Only the relevant changes are now visible. Pasting the details from the
previous pull request (#2331) here:
Added offset parameter for the following processing time window assigners:
ProcessingTimeSessionWindows
SlidingProcessingTimeWindows
TumblingProcessingTimeWindows
The offset is an optional parameter that can be added while creating these
classes, and it can be supplied as a long value or a TimeZone.
Test cases for the change are present in WindowAssignerOffsetTest. There
are tests for positive, negative and TimeZone offsets for each of the classes.
All Travis CI jobs passed.
I haven't done it for the event time window assigners yet - I can add that
if this is all right.

> 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.
