You can always change the alarm, or turn it off as well. The alarm time is of course retained once set, so simply set once and forget it. Any sims in that room will wake up to the loud noise of the alarm at the selected time. Once placed, simply click the clock and choose what hour you want the alarm to ring.

The last one being a wind-up alarm clock has the additional feature that it doesn't require power to operate, so your sims can't wake up late just because the power got turned off during the night! These clocks are available for purchase in the bedroom and electronics/miscellaneous categories: the IKEA PS Clock, CyberChronometer Alarm Clock, and the Get Up! Alarm Clock. With Elias943's gracious permission, I have included all three of his most excellent conversions modified to use this new tuning. The result was a new set of tuning which actually enables the clocks to wake up sims at the set time. So I set to work looking at how it could be done.

Elias943 had done a wonderful job on these TS2 to TS4 conversions, and I thought it was a shame that they didn't actually function. I had already written the Wakeup Early mod, which works well still (amazingly), but wouldn't it be nice to have actual alarm clocks? So I went on a search to find some, but the only alarm clocks I actually found were some static decorative alarm clocks. While designing a new bedroom for some recently aged up twins, I started thinking the larger family might require more preparation time in the morning for the kids to make it to school on time.
