It doesn't work on Windows (Win7 x64 / Strawberry Perl 5.18.1 MSWin32-x64-multi-thread).

VinsWorldcom@C:\Users\VinsWorldcom\tmp> client.pl
Time::HiRes::clock(): unimplemented in this platform at C:\Users\VinsW

According to Re: Script execution time, you can use POSIX to get similar functionality on Windows. In client.pl, I added:

#use Time::HiRes qw( time gettimeofday clock );
use Time::HiRes qw( time gettimeofday );
use POSIX qw(CLOCKS_PER_SEC);

and updated the following lines:

#    my $clock_t0 = clock();
my ($clock_t0, $clock_t1);
(undef, undef, $clock_t0, undef, undef) = POSIX::times();

...

#    my $clock_t1 = clock();
(undef, undef, $clock_t1, undef, undef) = POSIX::times();

... and it worked. Not sure if the "intent" is the same.

I don't see an SNTP module on CPAN. Have you considered make the code a module "Net::SNTP" and including the client and server as bin/ scripts?
