The Perl module Time::HiRes in Debian stretch does support nanosecond
resolution for stat() but not for utime(), although Linux has the
utimensat() system call providing that function.
$ cat /etc/debian_version
9.9
$ perl -e "use Time::HiRes qw(stat);"
$ perl -e "use Time::HiRes qw(utime);"
"utime" is not exported by the Time::HiRes module
Can't continue after import errors at
/usr/lib/x86_64-linux-gnu/perl/5.24/Time/HiRes.pm line 68.
BEGIN failed--compilation aborted at -e line 1.

BTW, Ubuntu 18.04, with perl 5.26, supports this:
$ cat /etc/debian_version
buster/sid
$ perl -e "use Time::HiRes qw(stat);"
$ perl -e "use Time::HiRes qw(utime);"
$
What's the reason for this and can I enable utime() with nanosecond
support in Debian stretch?
