How to display the current day value in Numbers app?

Question

In Numbers 3.2.2, where the current date and time happens to be 17 Dec. 2014 11:46am:
What formula will display the current date's numeral value?
What formula will display the current month's short name as text?
What formula will display the current year in four digits?
What formula will display the current time in the style "11:46am"?
Appreciated.

I've taken the liberty of tweaking that handy script to format the date as requested by the OP:
on run {}
  set right_now to (current date)
  set short_month to text 1 thru 3 of (month of right_now as string)
  set the_year to year of right_now as string
  set the_day to day of right_now as string
  set short_time to text 1 thru 5 of time string of right_now
  set the_secs to time of right_now
  if (the_secs / 2 as integer) < 21600 then
  set am_pm to "am"
  else
  set am_pm to "pm"
  end if
  set s to space
  set text_date to the_day & s & short_month & ". " & the_year & s & short_time & am_pm
  set the clipboard to text_date
  my paste_date()
end run
on paste_date()
  tell application "Numbers"
  activate
  tell application "System Events"
  keystroke "v" using {command down}
  end tell
  end tell
end paste_date
This considers 11:59:59 to be "am" and 12:00:00 to be "pm". (Edited after further consideration.) It has to be run either as an Automator service, or saved in ~/Library/Scripts/Applications/Numbers/ and run from Numbers' script menu. If run from Script Editor, it pastes the date into the end of the script itself.
Hope it helps,
