In the kernel, you have the time_capacity attribute that matches the
meaning of time capacity of ARINC653. The time capacity is NOT the
deadline. This is not an absolute time but a time quantum. This is the
maximum processing time that could be used by a process (let's say the
maximum execution time) whereas the deadline is an absolute time for the
completion of its work.
Hope that it clarifies these points :-)
