compares the top item on the stack to the nLockTime field of the transaction any of the following conditions are true, the script interpreter will terminate
containing the scriptSig. If that top stack item is greater than the transaction's with an error:
nLockTime field the script fails immediately, otherwise script evaluation continues
as though a NOP was executed. * the stack is empty; or
* the top item on the stack is less than 0; or
* the lock-time type (height vs. timestamp) of the top stack item and the nLockTime field are not the same; or
* the top stack item is greater than the transaction's nLockTime field; or
* the nSequence field of the txin is 0xffffffff;
Otherwise, script execution will continue as if a NOP had been executed.
