pskc_get_key_data_timedrift(3)	    libpskc	pskc_get_key_data_timedrift(3)

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  con-
       tains  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	 exam-
       ple,  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.
