The function doesn’t support these formats:

- Dates in which the day includes a suffix, such as `August 5th, 2025` or `5th August 2025`.
- Numeral notation with the date listed first, such as `5/8/2025` to represent August 5, 2025.
- Month names in languages other than English, such as `5 août 2025`.
- Dates that include any numerals other than western Arabic numerals, such as `٢٠٢٣/٨/٥`.
- Dates based on any calendar system other than the Gregorian calendar, such as `11 Av, 5785` or `11 Safar, 1447`.

## 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.

```js
<script runat="server">
  Platform.Load("Core","1");
  var convertedDateTime = DateTime.SystemDateToLocalDate(Now());
</script>
<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 system time for the user is August 5, 2025 at 12:34:56 PM and the user's account is in the Central Standard Time zone, the function outputs the system date and time.

```
Tuesday, August 5, 2025 1:34:56 PM
```
