NAME

       pskc_get_key_data_timedrift - API function

SYNOPSIS

       #include <pskc.h>

       uint32_t pskc_get_key_data_timedrift(pskc_key_t * key, int * present);

ARGUMENTS

       pskc_key_t * key
                   a pskc_key_t handle, from pskc_get_keypackage().

       int * present
                   output variable indicating whether data was provided or not.

DESCRIPTION

       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.

RETURNS

       an integer holding the content.
