+	* include/time.h (__clock_settime64):
+	Add __clock_settime alias according to __TIMESIZE define
+	* sysdeps/unix/sysv/linux/clock_settime.c (__clock_settime):
+	Refactor this function to be used only on 32 bit machines as a
+	wrapper on __clock_settime64.
+	* sysdeps/unix/sysv/linux/clock_settime.c (__clock_settime64): Add
+	* sysdeps/unix/sysv/linux/clock_settime.c (__clock_settime64):
+	Use clock_settime64 kernel syscall (available from 5.1+ Linux)
