The portable clock_gettime implementation had been using CLOCK_MONOTONIC to support its use as a PSP timebase for some platforms that used it this way. However with updates on the PSP side this is not required anymore. Preference should be to use CLOCK_REALTIME as it better aligns with the described semantics of the OSAL clock function, and makes for a better default. This can still be easily changed back if the user desires.

Describe the contribution
The portable clock_gettime implementation had been using CLOCK_MONOTONIC to support its use as a PSP timebase for some platforms that used it this way. However with updates on the PSP side this is not required anymore.

Fixes #844
Testing performed
Build and sanity check CFE, run all unit tests
Expected behavior changes
OS_GetLocalTime() and OS_SetLocalTime() will work as described.
System(s) tested on
Ubuntu 20.04
Additional context
This depends on not using the OSAL clock as a monotonic timebase. nasa/PSP#285 is required to fix this.
