CLOCK_MONOTONIC

[Mark Rush]

I hope I am addressing this to the correct audience.  But, I have recently
discovered that CLOCK_MONOTONIC seems to have been removed from
/bits/time.h.

I need a clock that is guaranteed to be monotonic - that is, it won't change
directions in the case of a system time change.  If anyone knows why this
particular #define was removed and what I should replace it with, I would
appreciate hearing.

Thanks
