It's a difficult one, as to someone with an all-singing, all-dancing
AWS, they can't understand why rainfall should be 'artificially' defined
to the 09-09 standard, but if you can record *both* periods (and keep a
careful distinction between the two), then that would be useful.

I keep just one, 00-24. It will surely become a standard in years to come.
However, I have all the data (mostly 10 minute readings), and if anyone
really wants to examine my records at some point in the future, they can
if they wish work out the 9:00-9:00 figures - or indeed whatever takes
their fancy.
