I'd like to get those in better shape before marking this ready for review. |

Question ... would the proposed k_clock APIs be better served somewhere under /subsys as something like sys_clock APIs? I am wary of them being placed under /kernel. |
It might be possible to reuse existing APIs for calculating some of those things though. |

Presumably the time testsuite was separate from the c library set of testsuites because it had a depedency on POSIX. Since that dependency no longer exists, colocate the time testsuite with the other c library testsuites. Signed-off-by: Chris Friedt <[email protected]>

Use the newly added sys_clock API in lib/os for * clock_gettime() * clock_settime() * clock_nanosleep() and nanosleep() * gettimeofday() Signed-off-by: Chris Friedt <[email protected]>
The ISO C function time() should not depend on POSIX and this was corrected recently via the common libc time() implementation. Remove this dependency from the network subsystem where it has been unduly needed for some time. Similarly, XSI_SINGLE_PROCESS was a dependency for time() via picolibc, because the time() implementation in picolibc relies on the POSIX gettimeofday() call. However, since Zephyr's common libc time() implementation no longer depends on that, it can be removed as a dependency in the network subsystem as well.

Remove POSIX_TIMERS and XSI_SINGLE_PROCESS dependencies from the aws cloud sample and the lwm2m client sample, as they are no longer required. Signed-off-by: Chris Friedt <[email protected]>

This change removes the dependency that exists between POSIX and some libc's by creating a mutual dependency of both POSIX and the common C library.
For a number of samples and tests, we remove the explicit dependency on POSIX_TIMERS and XSI_SINGLE_PROCESS where it really should not be required.
Please see individual commits for details
Should be merged after #90060
