Hardly seems worth the effort, but
precmd() {
thisminute=$(print -P %D{%M})
[[ $thisminute = ${lastminute:-0} ]] && {
PS1="%D{%I:%M}> " ||
PS1="%(t.Ding\!.%D{%I:%M})> " }
lastminute=$thisminute
}

Any variable you set in a function is set in the "parent" shell. Functions
run in the same context as builtins, by definition.
