+## (Debian Bug #607736)
+##
+## Original patch to make Timeticks works as in check_snmp v1.4.14, it turns
+## out is_numeric isn't so useful and treating all types as numeric works
+## best for backwards-compatibility. This is how it used to work in 1.4.14.
+##
+## As a special case, I also make calculate_rate look up for numeric values
+## as it would otherwise return the last value instead.
