Remove 'clock()' implementation, print warning

Browse Source 
FreeBSD implements 'clock' with an accuracy of 128 ticks-per-second for
compatibility reasons, Linux uses 1000000 per-second. Remove 'clock' and
print an error because it is unlikely that this is the resolution
expected by the application.

Fix #3057
