==== Check Lock Time Verify (CLTV)
((("Check Lock Time Verify (CLTV)", id="cltv07")))((("timelocks", "Check Lock Time Verify (CLTV)")))((("scripting", "timelocks", "Check Lock Time Verify (CLTV)")))((("bitcoin improvement proposals", "CHECKLOCKTIMEVERIFY (BIP-65)")))In December 2015, a new form of timelock was introduced to bitcoin as a soft fork upgrade. Based on a specifications in BIP-65, a new script operator called _CHECKLOCKTIMEVERIFY_ (_CLTV_) was added to the scripting language. +CLTV+ is a per-output timelock, rather than a per-transaction timelock as is the case with +nLocktime+. This allows for much greater flexibility in the way timelocks are applied.

In simple terms, by adding the +CLTV+ opcode in the redeem script of an output it restricts the output, so that it can only be spent after the specified time has elapsed.
