How to set up the calendar when Service Providers and Clients are in different timezone

Hi,

What would be your recommendation to set up the calendar when Service Providers and Clients are in different timezone?

In our case, our Service Providers are in the U.S. while Clients are outside of the US. What timezone does the calendar show and what if we need to change it to that of our clients's? How to configure the plugin? Is it even possible to do it?

In such case, is it possible to have calendar show time and appointments that are local to whoever uses it? Say Service Provider has her calendar that's in her timezone and client has his in his timezone?

Thank you,
