Severity:    
Problem:     

Posix.ProcEnv.times raises a Time execption on machines with large uptimes, in
particular, when the uptime is such that the number of clock ticks is >= 2^31.
This happens because the times function is returning an unsigned integer number
of clock ticks, which is being treated as signed, and hence is thought to be
negative.
