       Get the PSKC KeyPackage Key Data TimeDrift value.  This element contains the device clock drift value for
       time-based  OTP  algorithms.  The integer value (positive or negative drift) that indicates the number of
       time intervals that a validation  server  has  established  the  device  clock  drifted  after  the  last
       successful  authentication.   So, for example, if the last successful authentication established a device
       time value of 8 intervals from a specific start date but the validation server determines the time  value
       at 9 intervals, the server SHOULD record the drift as -1.

       If present is non-NULL, it will be 0 if the field is not present or 1 if it was present.
