No I don't. If they self-adjust, no effort is necessary on my part. Good thing, too, cuz we got the land line, each family member has their own cell, wife & I each have a PTT from our respective work, & there are 3 1/2 computers in the house. Bad enough I have to reset every TV-VCR-DVD-alarm clock every time the power blows (about once a month usually), at least I have some devices smart enough to figure out time on their own.

Just remembered another clock I don't have to worry about; my GPS. Couldn't set the time on that if I wanted, it checks in with the satellites all by its lonesome.
