help.rs suggests 'rustup install nightly-2014-12-18', which fails

rustup toolchain help

says

'channel' is either a named release channel or an explicit version
number, such as '1.8.0'. Channel names can be optionally appended with
an archive date, as in 'nightly-2014-12-18', in which case the
toolchain is downloaded from the archive for that date.

However:

cxh@swarmnuc001:~$ rustup install nightly-2014-12-18
info: syncing channel updates for 'nightly-2014-12-18-x86_64-unknown-linux-gnu'
error: no release found for 'nightly-2014-12-18'
cxh@swarmnuc001:~$ 

This happens for me under Mac OS X El Capitan, RHEL 6.x and Ubuntu 14.x

rustup install nightly-2015-03-01

works and seems to install a 1.0.0 version.

Probably the thing to do is to modify rustup.rs/src/rustup-cli/help.rs to use a date that works.

Likely a duplicate of #761.
