I have just seen that there are some questions here about the unlock_time feature. I never heard about the fact that Monero had something like that enabled, so I was trying to find out more about it, but nothing comes up in the help of either monerod or monero-wallet-cli.
How can I access that feature, and how exactly does it work? I mean, I know the idea that the output would only be used in a transaction after some point in time, or block height, but what are the commands and options, and in what environments is it available?
