Hello everybody,

I=92m exploring Flink options to build statistics engine for call center so=
lution.
One thing I=92m not sure how to implement.

Currently have the following jobs in the architecture.

Job #1 =96 is for matching start and end events and calculate durations. Li=
ke having call started and call ended events it is possible to calculate ho=
w long was the call.
Job #2 =96 is for aggregating precomputed values using multiple time window=
s, like 1 hour, 1 day, 1 week. (can we define time windows run-time by the =
way?). Also it joins control stream to care of subscription requests.

Supervisors, who consume the statistics, are spread around the world and ca=
n work in different time zones.
So, having time window defined as 1 day results in different data for Europ=
ean and American supervisors at exactly the same moment.

I=92m not sure how to achieve that with Flink.
What are the best practices to work with different time zones? Any hint is =
appreciated.

Thanks,
Alex
