Timeout calculations are error-prone for compound IPC operations

Consider a use-case where a top-level IPC operation has a logical timeout value.
If this operation is implemented as composition of sends, waits and semaphore waits, then it's cumbersome to pass correct timeout values for each of the calls.

Clients should be able to pass timeout in seconds relative to current time (possible today)
Clients should be able to pass timeout as absolute point of time (not possible today)
