We use it in an automated test of the Linux system time on an embedded system. Recently we fixed a kernel bug introduced by one of the 3rd party patches that caused a huge (0.01%-0.1%) drift of the CLOCK_REALTIME due to incorrect PLL initialization. The corresponding test based on hwclock's compare is now added to our automated test system. The test runs hwclock -c forever and fails if any drift anomality is discovered. Looks like hwclock -c works correctly at least in our case. I think it could be rewritten using clock_gettime() instead of gettimeofday().
