http://www.nist.gov/pml/div688/grp40/its.cfm under Daytime Protocol (RFC-867) contains the Health Field:
H is a health digit that indicates the health of the server. If H = 0, the server is healthy. If H = 1, then the server is operating properly but its time may be in error by up to 5 seconds. This state should change to fully healthy within 10 minutes. If H = 2, then the server is operating properly but its time is known to be wrong by more than 5 seconds. If H = 3, then a hardware or software failure has occurred and the amount of the time error is unknown. If H = 4 the system is operating in a special maintenance mode and both its accuracy and its response time may be degraded. This value is not used for production servers except in special circumstances. The transmitted time will still be correct to within ±1 second in this mode. If you (or someone else) has a log of these values, you could point out when the problem happened. Not sure if you even use this protocol, but I am pointing out the NIST does do error checking and the user (or IBMs software) needs to notice the error indicator.
