# [NAME](#NAME)

pskc\_set\_key\_data\_timedrift - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <pskc.h>**

**void pskc\_set\_key\_data\_timedrift(pskc\_key\_t * key, uint32\_t timedrift);**

# [ARGUMENTS](#ARGUMENTS)

[pskc\_key\_t * key](#pskc_key_t)

a **pskc\_key\_t** handle, from **pskc\_get\_keypackage()**.

[uint32\_t timedrift](#uint32_t)

the time drift value to set.

# [DESCRIPTION](#DESCRIPTION)

Set 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.
