(a) Just to interject a small point here: timestamps should never be used in any
algorithm as a substitute for an explicit sequencing number - for messsages
that have to be sequenced, because 1 second is just not high enough 
resolution, in fact there is no resolution high enough.

(b) Having read the whole thread and done a *lot* of date arithmetic in my time,
I have to side with those who think one big number, the number of seconds from 
some arbitrary starting point (say: midnight of the day before release 0.0
of Jabber) is the right way to do timestamps.  The main reason is that the 
client implementations will be more likely to be correctly coded.  

To make sure coders get the calculation right, post a piece of generic C code 
that does the conversions correctly gives as examples the correct 
timestamp-yyyymmdd pairs for a few dates... time 0; time exactly one day after 
time 0; time now (roughly); time sometime in the future; etc.
