I believe Biff's assumption is correct, why would someone use subtract if
they mean in the future,
I mean if the OP would have said subtract 3 hours from 15:00 it becomes even
more clear.
OTOH if someone says 3 hours from now it means 3 hours into the future. In
this case
I would go with Biff's assumption.

That'd be three hours ago. Assuming "three hours from now" means three
hours
in the future, use plus rather than minus; but the principle is correct.
