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';
