My Playbook's battery won't last for long, so I bought a dock for it.
I wish I can use it as a desktop clock or media player.
But the only issue is the OS doesn't allow Playbook screen to last for more than 5 minutes(even with external AC power).
Could anyone help me ? Thank you.

Depends on what is running on the device.... there are apps that will keep the PlayBook from going into Standby.

There was a 3rd Party Alarm Clock apps that had this option, but it was a paid app... and I don't remember what it was.

Media Player does it own it's own... if you have active media playing.

Battery Guru had a keep display awake option... but you had to keep it visible on the screen for it to work.

Not very elegant but it may be the only way.
