This is another API specified by the Single Unix Specification and POSIX*. It offers a monotonic system clock which is not affected (for good or bad) by NTP, but the current implementation in Linux*/
glibc
 does not provide better timing through this API than through
gettimeofday()
. Intel® Trace Collector does not support this API.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
