sftp-server needs to check whether localtime() has failed and must not pass a
NULL pointer to strftime() - this would lead to a segfault crash.
cd freebsd-src/crypto/openssh
git grep -B 1 -n localtime sftp-server.c
sftp-server.c-1015- strftime(buf, sizeof(buf), "%Y%m%d-%H:%M:%S",
sftp-server.c:1016: localtime(&t));
--
sftp-server.c-1072- strftime(buf, sizeof(buf),
"%Y%m%d-%H:%M:%S",
sftp-server.c:1073: localtime(&t));
--
sftp-server.c-1495- strftime(buf, sizeof(buf), "%Y%m%d-%H:%M:%S",
sftp-server.c:1496: localtime(&t));
