iOS widget is not updating time regularly. I know it’s not your fault, it’s because of iOS limitations for efficiency. Sometimes the time difference is multiple hours which makes it unreliable to quickly glance at it for time in different timezone. If I have to open the app for time anyways, widget seems useless.

A tiny timestamp on the widget can be helpful which shows when the time was updated last or tiny text that says . If current time and the timestamp are too far away, I can decide to open the app by tapping on the widget.
