Do one thing, and do it well. What you have proposed involves:
 * an additional force flag
 * interpolation of what follows the force flag (does m mean minutes, or
months?)
 * expectations around time, time zones, and what an hours is.

That fails the litmus test on complexity for me personally - it seems like
a lot of complexity for not much gain.

This isn't a good reason for adding another non-portable feature.
