Clocks and timers
Additional options on ovens include clocks, timers, 'memory-programmed settings', and bells or buzzers to announce when the cooking is done.
A delayed-start timer or auto-timer allows you to preset the oven times, put a dish in the oven and then go out: the timer will start the oven while you are away in order to deliver a fully cooked meal just in time for your return.
Such devices are useful, provided that they are relatively simple: you may not use a complicated timing device often enough to remember quite how it works without consulting the manual. A delayed-start timer may sound appealing, but how often will you actually use one? And can you really trust it?
