No warning for start date before entry date

When I create a task where I have already worked on, I enter it and set the start time to some time ago. Then I get the warning:

Warning: You have specified that the 'entry' date is after the 'start' date.

I don't see the point of this warning - is it so unusual to enter a task after you have started it?

It may be useful if you accidentally start a task 10 months ago instead of 10 minutes ago because you thought `-10m` would mean minutes. Maybe there should be a threshold above which the warning will be issued, something like

Warning: The 'start' date is over a day ahead of the 'entry' date.
