Exercise Idea: Global Meeting

[ErikSchierboom]

In order to have more date/time/timezone exercises, I came up with something like this:

The story is that the company you work in has gone fully remote: all employees are working from home. This has lead to people all over the world to joining the company, which has been great. Scheduling online meetings though has become quite hard, having to consider different time zones, preferred working hours and such.

The exercise could take a list of employees with their time zones and preferred working hours and having the student try to find the hour which all employees can participate.
