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.
