I have two computers, one laptop, one car, one car radio, one satellite radio, and one alarm clock.
The computers and the laptop automatically deal with daylight savings. The satellite radio gets its time from the satellite stream, so it's constantly synched to the atomic clock.
This means the only things I need to set the time on are the alarm clock, the car, and the car radio. So far, this is quite a bit easier than having to remember every device - *something* that autocorrects will cue me. But it's only a matter of time before all my gizmos except one autocorrect, and then I'm pretty much guaranteed to forget about that one.
