- Similar assumption as 24h per day:
365 days per year, ignoring DST and leap-years
Very old resources (older than 2 years) are printed as `2y15d` instead of using just the number of days.
This leads to parser errors for namespaces in rancher:
```
2025/08/18 14:43:34 [WARNING] convert timestamp value: 2y114d failed with error: strconv.ParseInt: parsing "2y114d": invalid syntax
2025/08/18 14:43:34 [WARNING] convert timestamp value: 3y50d failed with error: strconv.ParseInt: parsing "3y50d": invalid syntax
2025/08/18 14:43:34 [WARNING] convert timestamp value: 2y163d failed with error: strconv.ParseInt: parsing "2y163d": invalid syntax
2025/08/18 14:43:34 [WARNING] convert timestamp value: 3y50d failed with error: strconv.ParseInt: parsing "3y50d": invalid syntax
```
