I been using third party apps / widget till now to always view Date & Time of secondary region on my Redmi Note 7 on Global Stable MIUI|
Recently I noticed that Settings menu and widget section already has option to show dual-clock widget
This works smoothly, has same big appearance as default clock appearance and is useful for those who work & need to frequently see other time zones
The third party widgets that I used till now been lagging in updating time correctly, I would see 10 to 20 minutes lag / delay in their time reflection. But this inbuilt MIUI Widget works in real time.
Big Thanks to Xiaomi and MIUI Developers and those who initiated this.
