Good question. I'd much rather just keep using ntpdate. The ntpd man page is
obviously wrong when it suggests that 'ntpd -q' mimics the behavior of
ntpdate - it doesn't - 'ntpd  -q' is dog slow. Along comes 'sntp -r' to the

Very interestingly, 'sntp' is distributed in the ntp emerge package on
Gentoo. However, on Ubuntu, the ntp deb package does not include sntp. In
fact, it doesn't seem like sntp even exists in any package in Ubuntu. I did
find the deb package 'msntp' on Ubuntu,  which has the binary 'msntp' which
seems to perform exactly like the 'sntp' binary on Gentoo. The man pages
also look suspiciously similar. Go figure.
