The author could have anticipated that you might want to do it, I guess!
I'll write a more sophisticated version of plot and axis for POSIXt classes
for 1.4.0: what is there was intended to be a quick hack to encourage
migration from chron classes.

I suppose you can't upgrade R either, then? We would encourage people to
go to 1.3.1: it had a lot of bug fixes, and we do not anticipate any
further releases before 1.4.0 which `is not yet scheduled, but is likely to
be around the end of 2001.'
