Need help Database

Hi @emmanuel @NigelG ,
I have a Page where we take user’s information to create their profile. There is a Search box on the page to select a timezone. I have created the fields one of the geographic address where the user’s timezone Id will be saved and one of date type in which the user’s local time is saved based on the search box value.
But it’s not updating from time to time. What I really want is the user’s local time updates automatically, how can I do that?. It’s because I have to fetch that local time on other page.
