That would be nice yes.

You can turn around that in your date_in_prompt by using the SECONDS
variable.

Something like:

init_prompt() {
  set -- $(date +'%k %M %S')
  start_sec=$(($1*3600+$2*60+$3))
  day=-1
}

init_prompt

prompt_basic='\t\$ '

date_in_prompt() {
  PS1=$prompt_basic
  local new_day=$(( (SECONDS+start_sec)/86400 ))
  if (( new_day > day )); then
    day=$new_day
    PS1="\d\n$PS1"
  fi
}
