There's nothing in your "Remote Date and Time" field:
"Remote Date and Time
You can assign an analog or digital tag or an expression to this control. The application reads the value of this control and, when it changes from zero to a non-zero value, updates the application terminal’s internal clock with the values in the Remote Year, Remote Month, Remote Day of Month, Remote Hour, Remote Minute, and Remote Second controls. Only the time elements to which controls are assigned are used to update the internal clock."
