You can already do this interactively with PROMPT_COMMAND, e.g.

  PROMPT_COMMAND='date=$(date +%D);time=$(date +%T)'

Not quite - that is run before your prompt is displayed.

  $ PROMPT_COMMAND='time=$(date +%T)'
  $ echo $time;date +%T
  12:19:07
  12:20:19
Thus it will show the time after your last command returned rather than the current time.
