In the August features announcement about new features in SharePoint, I see my old arch-enemy, World Clocks and Time Zone webparts make an appearance. I never have had much use for these web parts personally. And honestly, I've never really understood their appeal beyond usenet groups and Myspace, when they were standard attributes.
But I am wise enough to know that my way isn't the only way, and over time I have been repeatedly surprised by enterprise clients who really, really love these web parts.
Over the years I've had to build custom code web parts to display the time and date. With Office 365 and SharePoint Online, there have been a few solutions around for the last year or so available on Github or via third parties, but now there is a built-in weather and world clock web part option for modern page layouts.
There are lots of other neat features too - call to action buttons, hero web part updates, News and announcement rollups - but what I'm betting right here and now that the biggest "wins" out of this rollout will be the time and weather features.
