It is common place to use 4 standard 7 segment displays with the first and
third turned up-side down. (only the 'G' segment and decimal point swap when
a display is up-side down).

This will put the first decimal point at the top left of the display (use it
to indicate pm) and the second and third decimal points vertically in line
in the middle of the display (flash this pair on for half a second each
second). The last decimal point can be used as an indicator for anything you
need, say 'alarm set'.  Or use any layout you fancy.

When you wire up the displays and store the patterns for the digits make the
decimal point the least significant bit, then you just have to add 1
(increment) to turn on the decimal point indicator or decrement 1 to turn it
off.
