Re: Bug#352610: Please create a udeb for ntpdate
NTP is something I know a bit about.
Yeah, ntpdate will do the job, and it's a good bit smaller than the
full ntp-simple package.
The alternative you were thinking of *may* be "chrony".
Both implement enough of the network time protocol (NTP) to do what
However, keep in mind that NTP, by it's very nature, needs access to
a network time server. The operative word here is "network". If you
don't have access to the global internet, and you don't have an NTP
server on your local network (or you're doing an install without any
network connection at all for some reason) both ntpdate and chrony
will fail. You need to think hard about what you want to do under
those circumstances. Is it acceptable to have the d-i ask for the
address of an NTP server at the same time as it's asking for other
network parameters? For what it's worth, some DHCP servers will
allow you the option to ask for the address of a preferred NTP
server. But if you use this option, you need to think about what to
do if it fails.
Doing something that will work in the easy cases is pretty straight-
Getting the corner cases right is non-trivial.

Yes, otherwise we e.g. end up with a filesystem that was modified in
1970 and e2fsck will complain on the next boot.
Since I filed this bug, someone suggested that a tool other than ntp
might be better since it's smaller. Unfortunately, I cannot remember
the name right now. I'm CCing -boot so other people can comment, but
unless there are great ideas, I'm still interesting in having an ntp
