It seems that saving and restoring the glob doesn't work, but saving and restoring the CODE entry in the glob works for me:

perl -MTime::HiRes -le "my $x=*Time::HiRes::gettimeofday{CODE};*Time::
+HiRes::gettimeofday = sub(){42};print Time::HiRes::gettimeofday; *Tim
+e::HiRes::gettimeofday = $x;print Time::HiRes::gettimeofday"

or, reformatted and untested:

use strict;
use Time::HiRes;

my $x=*Time::HiRes::gettimeofday{CODE};
*Time::HiRes::gettimeofday = sub(){42};
print "Modified: ", Time::HiRes::gettimeofday,"\n";
*Time::HiRes::gettimeofday = $x;
print "Restored: ", Time::HiRes::gettimeofday
