time lock

A time lock is a lock that is controlled by clockwork and prevents it from being opened before a specific time. These devices were first used in 1858. Clocks, in general, are machines that use a mechanism performing regular movements at equal intervals to track time. Early mechanical clocks were large and housed in towers, striking only the hours. Over time, clocks became smaller and more portable, with advancements like the pendulum and spring-driven mechanisms improving accuracy. Modern timekeeping relies on highly precise devices, including atomic and quartz clocks.12
