For now, implementing timelocks is a property best left to the experts.
Coinb.in is one such service. As the site simplifies: “Use OP_CHECKLOCKTIMEVERIFY (OP_HODL) to create a time locked address where the funds are unspendable until a set day and time has passed”. All of the site’s code can be audited on Github and the site doesn’t deny your private keys.
