Just for your information:

In our Python implementation of a fuzzy timestamp type we
used accuracy values ranging from 1 to 7 denoting the
"precision" of a complete timestamp definition:

7 - full subsecond accuracy (7 "digits" precision)
6 - seconds
5 - minutes
4 - hours
3 - days
2 - months
1 - years
