typo with (intended) use of CLOCK_MONOTONIC

[rgalonso]

In the definition of void getTimeMonotonic, there is a section that checks whether to use CLOCK_REALTIME or CLOCK_MONOTONIC. This is conditional on the define CLOCK_MONOTINIC. Note the typo: monot-I-nic.

This is clearly a typo, but I'm not even sure whether CLOCK_MONOTONIC is the correct define. In another place in the code, there is a conditional block on _POSIX_MONOTONIC_CLOCK. The best explanation I found of one vs the other was a StackOverflow answer.
