Inputs

VAR_INPUT
    systemTime  : TIMESTRUCT;  (* Input time in system time format (struct) *)
    nBias       : INT;         (* Specifies the current bias, in minutes, for local time translation on this computer.
                                The bias is the difference between Coordinated Universal Time (UTC) and local time.
                                UTC = local time + bias *)    
    bUTC        : BOOL;        (* Specifies whether the systemTime is UTC or local time. *)
    nPrecision  : USINT(0..9); (* Precision. Number of decimal places of seconds. (0..9) *)
END_VAR
