# Checks if the system clock is sane between build timestamp and expiration date #

Reports, if clock is sane and not slower than build timestamp or faster than
expiration date (configurable, default currently set to 17 MAY 2033 10:00:00).

This should catch situations, where the host's clock is too much off (CMOS
battery defect, user mistakenly set a very wrong date, etc.), resulting in
network time synchronization tools (such as sdwdate) no longer being able to
correct the clock; catch eventual bigger bugs in network time synchronization
tools; and some types of attacks on network time synchronization.
