[Orgmode] Task time limit

[Sebastjan Trepca]

Hi,

another idea for a feature (if it's not already possible) that would
definitely come handy. I have few tasks that should only take a
limited amount of my time each day.

For example, "check the feed reader" would be set to 20 minutes. I
would clock-in the task, go and check the reader and after 20 mins,
alarm would go off, reminding me that I should start doing something
else.

Is this possible with current version?

Thanks, Sebastjan
