Convert a date/time string to a TDateTime value.

function StrToDateTime( |
const S: AnsiString |

const s: AnsiString; |
const FormatSettings: TFormatSettings |
):TDateTime; |
StrToDateTime converts the string S to a TDateTime date and time value. The date and time parts must be separated by a space.
For the date part, the same restrictions apply as for the StrToDate function: The Date must consist of 1 to three numbers, separated by the DateSeparator character. 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 not supported in Delphi)
The order of the 3 numbers (y/m/d, m/d/y, d/m/y) is determined from the ShortDateFormat variable.
On error (e.g. an invalid date or invalid character), an EConvertError exception is raised.
