Here's a easy, simple n silly trick to customize the system tray clock
for XP pro users:

step 1: goto start/run.
step 2: type regedit
step 3: goto HKEY_CURRENT_USER, expand it, expand Control Panel in it, select 'International'
step 4: you see two strings with values AM & PM each. click it n modify the values into something more interesting like 'Morning' for AM & 'Night' for PM.

for simplicity just copy paste the below path:
HKEY_CURRENT_USER\Control Panel\International

step 5: Reboot your PC and viola ! u see the difference

Isnt that funny n exciting !
