It's not supported. POSIX also specifies that how discontinuities should 
be treated on condition variables:

"For cases when the system clock is advanced discontinuously by an 
operator, it is expected that implementations process any timed wait 
expiring at an intervening time as if that time had actually occurred."

For windows, relative timeouts might be easy to implement, but not in POSIX.

Best,
