You can't just stick a named BLOCK there in the middle of an expression and expect it to work. If you use B::Deparse you'll see it's being parsed as trying to call the method BEGIN on the return value of a block with just time in it. 

sleep(4);
print(('timespan: ' . (time - do {
    time
}->BEGIN)));
