how to make the clock or date in the server, so that the time and date cannot be edited when the user uses the appsheet application
What kind of application are you trying to incorporate this into? Who will be using it?
Like attandance in the class who comming late
If you have a column in your table for the date/time, and you set that column as ‘uneditable’, with an initial value of now(), it will automatically capture the current day and time when the form is being completed. This field will not be editable to the app user.
