Thanks to those who responded either publicly or privately. In summary,
"infinite are the arguments of mages". Some take resolution to be a
near-synonym for precision, some take it to be a synonym for granularity.
The more definitive the source, the vaguer the definitions.

I should perhaps explain that I was interested in an internal
representation for durations, which I am now representing as a triple of
months, minutes, and seconds (the number of minutes in a month is not
predictable, nor the number of seconds in a minute given leap seconds,
but all other relationships are predictable: 10080 minutes/week, 12
months/year, 100 years/century, etc.) To this I would add a fourth
nonnegative integer representing "clock resolution units" and wanted to
make sure I had the terminology correct.

Ah well.
