/****************************************************************************
* Name: futimes
*
* Description:
* futimens() update the timestamps of a file with nanosecond precision.
* This contrasts with the historical utime(2) and utimes(2), which permit
* only second and microsecond precision, respectively, when setting file
* timestamps. With futimens() the file whose timestamps are to be updated
* is specified via an open file descriptor, fd.
*
* Input Parameters:
* fd - Specifies the fd to be modified
* times - Specifies the time value to set
*
* Returned Value:
* On success, futimens() return 0.
* On error, -1 is returned and errno is set to indicate the error.
