New Revision: 272678
URL: https://svnweb.freebsd.org/changeset/base/272678

Log:
  Back out timegm error check from r272562.
  
  POSIX treats negative time_t as undefined (i.e. may be valid too,
  depends on system's policy we don't have) and we don't set EOVERFLOW
  in mktime/timegm as POSIX requires to surely distinguish -1 return
  as valid negative time from -1 as error return.
