time/clock always on? I need to have the time/clock on for about 30 mins. Just the time I can see in dark. The screen doesn't turn off.

Is there any application or way I can have the time on for xx minutes in case I need it?

Keepscreen can let you choose some applications and select a specific screen timeout for each of them. So you could just set the Clock application with the "no timeout" option.
