This is the Y2106 problem: representing a timestamp using an *unsigned* 32-bit integer number of seconds since the Unix epoch only allows representing ~136 years since 1970. If you use a *signed* 32-bit integer you get the more famous Y2038 problem. There are other instances of the Y2106 bug in the archive, e.g. BIND's struct isc_time also represents seconds since the epoch with an unsigned int. -- Robert Edmonds edmo...@debian.org
