Diferencia de minutos entre dos TDateTime

De hecho me interesa recuperarlo como entero para saber si hay una diferencia menor a 10 minutos pero la verdad soy nuevo en esto y estaba investigando pero me he confundido más :s. Saludos!.

Talvez solamente necesitas esto:

Código Delphi [-]
if MinuteSpan(tiempo1,tiempo2) > 10 then
begin
    // ....
end;

Saludos,

PD.: Ten cuidado con la función StrToDateTime. Según la ayuda de Delphi:

Converts a string to a TDateTime value.

Pascal
function StrToDateTime(const S: string): TDateTime; overload;
function StrToDateTime(const S: string; const FormatSettings: TFormatSettings): TDateTime; overload;

File
SysUtils

Description
Call StrToDateTime to parse a string that specifies a date and time value. If S does not contain a valid date, StrToDateTime raises an EConvertError exception.

The S parameter must use the current locale's date/time format. In the US, this is commonly MM/DD/YY HH:MM:SS format. Specifying AM or PM as part of the time is optional, as are the seconds. Use 24-hour time (7:45 PM is entered as 19:45, for example) if AM or PM is not specified.

Year values between 0 and 99 are converted using the TwoDigitYearCenturyWindow. This value is stored either in a global variable (first form) or as a field in the FormatSettings parameter (second form) See "Currency and Date-Time Formatting Variables" for more information.

The first form of StrToDateTime is not thread-safe, because it uses localization information contained in global variables. The second form of StrToDateTime, which is thread-safe, refers to localization information contained in the FormatSettings parameter. Before calling the thread-safe form of StrToDateTime, you must populate FormatSettings with localization information. To populate FormatSettings with a set of default locale values, call GetLocaleFormatSettings.
