Sprint Event Schedule for Distributed Teams with Timezone Differences

How do team members usually collaborate with each other throughout each working day?

What @Ian Mitchell said and what do the teams think would be the best way to do this?  Also, have you asked the stakeholders what would work for them in the case of the Review?

The Scrum Guide doesn't say anything about this, and next to that, you don't HAVE to do anything. What does your team think is most pragmatic?

@Ian Mitchell we have our Daily Scrum everyday and everyone attends it. People use communicating tools since physical communication is not possible.

@Daniel Wilhite the team's current process exists only because things have been like that when people came in.

@Sander Dur but the Scrum Guide says that Sprint Review happens at the end of the Sprint, followed by the Sprint Retrospective prior to the next Sprint Planning.

Indeed. Than what would the team think is most convenient? 

So, if the process has existed prior to them team coming together shouldn't the current team has some say in how things should occur now?  The core concept of agile processes is the continuous inspection and adaption based on the information available now.  The current team should be allowed to determine what works best for them, not be expected to operate based on what worked for previous teams.  I guarantee that a lot has been learned since the previous team was doing the work. And the current team has a whole different set of knowledge on which to draw for their own decisions. Even if the stakeholders have been consistent, I would expect that they have learned a lot about how their interactions and information can be useful.

Do not try to make decisions for them team that is doing the work.  Let them decide what works best.  Don't try to make decisions for the stakeholders. Let them decide what works best for them to be able to interact effectively with the Scrum Team.  You should facilitate all of this discussion. Help them to realize that by providing input/feedback it will only make things better for everyone.

Notice that @Ian Mitchell, @Sander Dur and myself all are saying basically the same thing.  If the team isn't involved in any decision made, then the wrong decision is being made. Only the people doing the work can decide what works best. In this case, the Scrum Team and Stakeholders are the ones doing the work.
