You can use monent in a switch node to comapre time objects, You can tell moment the format of the input date.
$moment($$.payload."Notification Issued Date" & " " & $$.payload."Notification Issued Time", "DD/MM/YYYY HH:mm").isAfter($moment())
$$.payload."Notification Issued Date" & " " & $$.payload."Notification Issued Time"
is the same as "01/03/2024" + " " + "12:00"
"DD/MM/YYYY HH:mm" tells moment the forrmat to expect.
$moment() is the time/date now
