Task#timestamp returns Time.now when there are no prerequisites. This

yes, and tasks (non-file tasks) are always executed.
Only if #needed? returns true. Rake::Task#needed? does indeed return
true, but if I create my own task class which extends it, then I can
override #needed? to return false sometimes. However, #timestamp will
still return Time.now. Overriding #timestamp without duplicating the
code that checks prerequisites is not trivial.
Also, I think there's a mismatch: given two Rake::Task objects: task1
and task2, where task1 has a prerequisite on a file and task2 is empty,
task1 will return the timestamp of the file while task2 will return
Time.now, although both will always be executed.
