- 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 ``` Relates to https://github.com/rancher/steve/pull/684 Co-authored-by: Wolfgang Jung <wolfgang.jung@loewenfels.ch>
