About the Chicago-Riyadh gap
Chicago sits in the America/Chicago time zone (CDT), while Riyadh uses Asia/Riyadh (UTC+3). That puts Riyadh 8 hours ahead of Chicago right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
Standard working hours in these two cities do not overlap at all, so any live meeting requires someone to move outside 09:00-17:00. The table above marks the hours when both parties are at least likely to be awake.
