When I am using the function DateTimeToString with the parameter "01/01/1753" on my local machine I get the value "0-00-01 00:00:00".
On a development PC in the USA the resultiong value is "1753-01-01 00:00:00" (as expected).

On my local machine the parameter (Date("01/01/1753")) works as expected.


Code:
Object oDRReportHelper is a cDRReportHelper
End_Object


Object oButtonDateTime is a Button
    Set Location to 34 197
    Set Label to "DateTime"


    Procedure OnClick
        String sDateTimeResult1 sDateTimeResult2
      
        Get DateTimeToString of oDRReportHelper "01/01/1753" to sDateTimeResult1
        Get DateTimeToString of oDRReportHelper (Date("01/01/1753")) to sDateTimeResult2
      
        Showln sDateTimeResult1
        Showln sDateTimeResult2
        Showln
    End_Procedure
    
End_Object


Result:
0-00-01 00:00:00
1753-01-01 00:00:00
