Seems like 'utmp' was removed from FreeBSD-9 and later (replaced with 'utmpx'):

This one-liner fails on said system:
    $ perl -w -e '@d=localtime(72057594037927935);'
    Name "main::d" used only once: possible typo at -e line 1.
    localtime(72057594037927936) too large at -e line 1.
    localtime(72057594037927936) failed at -e line 1.

While it works on many other kernels (e.g. linux 64bit) even with older Perl 
versions.

Based on the comment in './tests/misc/date.pl' line 44 it looks like the value 
was chosen somewhat arbitrarily
to be very large but smaller than 2^64 (so it was chosen as 2^56).
Perhaps change it to 2^55 ?

From the same system:
    $ perl -w -e '@d=localtime(2**54);'
    Name "main::d" used only once: possible typo at -e line 1.
    $ perl -w -e '@d=localtime(2**55);'
    Name "main::d" used only once: possible typo at -e line 1.
    $ perl -w -e '@d=localtime(2**56);'
    Name "main::d" used only once: possible typo at -e line 1.
    localtime(72057594037927936) too large at -e line 1.
    localtime(72057594037927936) failed at -e line 1.
