You can use DATETIME_FORMAT for both 3 and 4. It is documented in the formula field reference.
For the time, you will probably also want to use SET_TiMEZONE to set the timezone or you will get the time as GMT time.
date
DATETIME_FORMAT(
  SET_TIMEZONE({Date & Time field}, 'Australia/Sydney'), 
  'M/D/YYYY'
)
time
DATETIME_FORMAT(
  SET_TIMEZONE({Date & Time field}, 'Australia/Sydney'), 
  'h:mm'
)
Note that you can also combine these formulas with formula use in step 2, to eliminate the field in step 2.
DATETIME_FORMAT(
  SET_TIMEZONE(
    DATEADD('1/1/1970',{Unix Timestamp},'seconds'), 
    'Australia/Sydney'
  ), 
  'M/D/YYYY'
)

Kuovonne to the rescue again! Thanks! The date and time formulas worked perfectly. The last formula didn’t work for me, but I don’t mind having an extra column that I could hide.  :slightly_smiling_face:

Some curly quotes snuck into the last formula when I copy/pasted from your earlier post. I edited my post to turn them in straight quotes, so you can try it again.
