Maybe it's just a my opinion, but I think we are talking
about two distinctly different pieces of functionality:


 (1) pretty-printing a given time via at-style-time specs...

  <RRD::TIMESTR 'some-strftime-format' 'some-at-style-time'>

 vaguely like GNU 'date --date "some-gnu-date-style-time"'


 (2) pretty printing the last update of a given RRD...

   <RRD::LAST 'some.rrd' 'some-strftime-format'>

 very much like 'rrdtool last some.rrd'.


Okay?  I don't really care about (1) but I need (2) before I
can migrate from MRTG to my RRDtool interface.

Just a thought: what about going with <RRD::TIME::TIMESTR> and 
<RRD::TIME::LAST> or somesuch?

later
