Solaris uses something that is nice for package revisions.  The package
revision includes the date formatted like 'YYYY.mm.dd.HH' IIRC.  So the
nightly builds can have a version like 1.2.1-917-f0a7accf1d68,2009.06.25.10
or something to that effect.

I think build numbers are inherently project- and team-specific.  Having
said that, a nice scheme for nightly Mercurial builds that works across
platforms and can be used for builds in Linux, BSD, Solaris and Windows
would be very good indeed.
