):TDateTime;

Description

StrToDateTimeconverts the string Sto a TDateTimedate and time value. The Date must consist of 1 to three digits, separated by the DateSeparatorcharacter. If two numbers are given, they are supposed to form the day and month of the current year. If only one number is given, it is supposed to represent the day of the current month. (This is notsupported in Delphi)

The order of the digits (y/m/d, m/d/y, d/m/y) is determined from the ShortDateFormatvariable.

Errors

On error (e.g. an invalid date or invalid character), an EConvertErrorexception is raised.
