Worked fine for a while, but in recent years hasn't. No matter how many time I chose UTC in the settings, it will always display local time in the widget. If I want to see the time I selected, I have to open the full app. No time won there, pun not intended. Keeps time perfectly fine, much better than what the cell network does. Doesn't seem to be supported anymore; which is a pain, given I paid for a license.

You can absolutely configure what time zone is shown in the widget. You can set it up while creating the widget. Can you write me a mail with more details on this problem?

Edit: Most of your other apps are rated at 4.8 and this is 4.7. I read the 1 star reviews for this and they are very infuriating. Sorry for the negative reviews for no reason at all. Review: Works perfectly! I love how it lists many NTP servers to choose from for easy config. I also love the widget for home screen display. For me, there is a space after the first slash when viewing the date in the app. Could you add a way to display the NTP time on the lock screen. That would be amazing!

Thanks a lot for the positive reviews. I guess there's nothing you can do about the bad reviews 💁 I very much appreciate that you took the time and wrote such a positive one! When setting up the widget you can edit the date format, maybe that helps getting rid of that extra space?

Only improvement would be to add an option that prevents the "jumping" when using 3 decimal places due to certain font settings. Other than that, thanks for building a useful app!
