I have a very simple SharePoint List that consists of five columns:

In PowerApps, in order to allow the user to update the Time_Out column in SharePoint, I have used the Patch function to change the record. The patch function is created in a button under the ONSELECT property as follows:
ViewForm(Form1);Navigate(DashboardScreen);Patch(E_Visitor_log2,Time_Out, {Time_Out: Now()})
However, I keep receiving an error stating it is the wrong data type:

Can anyone explain what am I misinterpreting to satisfy this simple patch function?
