Description
LWG-3504 condition_variable::wait_for is overspecified
We have _To_absolute_time(), but I don't immediately know whether it conforms to this LWG issue's resolution. This has been a notoriously tricky area for us to get right.

Research direction
Start with the referenced _To_absolute_time() implementation in stl/inc/thread at lines 166-180 and compare its behavior with the LWG-3504 resolution. Determine whether condition_variable::wait_for follows that resolution, then document or correct the implementation so the behavior is no longer overspecified.
