Example

To use the function, pass it a supported date-time string. This example uses the Now() function, which returns the current date and time.

1<script runat="server">
2  Platform.Load("Core","1");
3  var convertedDateTime = DateTime.LocalDateToSystemDate(Now());
4</script>
5<p><ctrl:eval format="F">convertedDateTime</ctrl:eval></p>

The example returns the current date as a timestamp and as a formatted string. For example, if the local time for the user is August 5, 2025 at 12:34:56 PM Eastern Standard Time, the function outputs the system date and time.
