World Timer Chrome extension

Hi mates,
This is 1-day-project about the idea of tracking your world team. As a chrome extension, it appears whenever you open the browser, shows you schedule ( mostly meeting) of offices in different timezones. This used to be pain in my ass when I work for people across countries.

If you guys have interest in this idea and can make live, I am happy to share my sketch design

Thanks @Tobias van Schneider for the amazing sketch plugin Color claim and weather icons by @Adam Whitcroft

P/S: you can spot one big mistake on the shot?
