NAME
Tie::Scalar::Epoch - Create a scalar that always returns the number of non-leap seconds since whatever time the system considers to be the epoch.
SYNOPSIS
# create a variable and tie
tie my $epoch, 'Tie::Scalar::Epoch';
print "$epoch\n"; # eg. 1351113480
sleep 2; # wait 2 seconds...
print "$epoch\n"; # ... 1351113482
# this will die; $epoch is a readonly variable
$epoch = '2012';
# don't die if no_die is true
tie my $epoch, 'Tie::Scalar::Epoch', { no_die => 1 };
$epoch = '2012';
