To assist project planning, TODO items can be labeled with a date and/or a time. The specially formatted string carrying the date and time information is called a timestamp in Org mode. This may be a little confusing because timestamp is often used as indicating when something was created or last changed. However, in Org mode this term is used in a much wider sense.
|• Timestamps:||Assigning a time to a tree entry|
|• Creating timestamps:||Commands which insert timestamps|
|• Deadlines and scheduling:||Planning your work|
|• Clocking work time:||Tracking how long you spend on a task|
|• Effort estimates:||Planning work effort in advance|
|• Relative timer:||Notes with a running timer|
|• Countdown timer:||Starting a countdown timer for a task|
