gad d3030167ea Add a check for wtmp records which have invalid values for ut_time. Wtmp ... records with time==0 get "the time of the last valid record", while records where time goes backwards (compared to the previous record) are skipped. Also prints a message saying how many records were changed or skipped due to these checks. Check was inspired by a simpler check in OpenBSD's version. This is all meant to sidestep problems that Tillman Hodgson noticed with 'ac' when running sparc64 with 64-bit time_t's. The real problem is whatever is creating wtmp records with ut_time==0, of course, but I have not yet figured out what is doing that.
