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.
