Hello Lanese, Joanne K. (AWM, USA),
The feature you're remembering is indeed available in Windows 10 and 11, though it requires a quick setup in the Clock settings.
To configure this, please right-click on the time and date in your system tray and select "Adjust date and time." In the settings window that opens, navigate to the related settings for "Additional clocks." Here, you can show up to two additional clocks by checking the "Show this clock" boxes.
You can then select your desired time zones and label them (e.g., "London," "Tokyo"). Once saved, you can simply hover your mouse over the time in your system tray to instantly see all the clocks you've configured, alongside your local time.
This is a very convenient feature for tracking international colleagues. I hope this step-by-step guide helps you get it set up.
Please let me know the update and if this answer resolves your question, please don't forget to hit "Accept Answer." 🙂
Jason.
