While wtmpdb(8) was independently written and pushed with the intention
of replacing wtmp(5), let's not confuse it with wtmp, which still exists
and works (modulo distro decisions...). It's not really the job of a
libc man page to point to the wtmpdb application. Note that the seconds
in wtmp proper are now unsigned, so you can get post-2038 dates.

(Yes, wtmpdb stores microseconds as determined elsewhere in the thread.)
