The only non-FIELD_STR atoms other than the date ones are "objectsize" and
"numparent". "objectsize" has an optional ":disk" modifier, but that doesn't
change formatting (just the value of the integer printed). "numparent"
doesn't have any modifiers, it just prints the integer number of parents.
Otherwise, everything is sorted by string value, so I think only the date
atoms have this kind of mismatch between formatted value and sort value.
