Is it possible to define repeating interval for every last day of month in terms of ISO 8601?
I need this for several Mesos/Chronos jobs.
ISO 8601:2004 does not specify.
ISO 8601-1:2019 and in particular ISO 8601-2:2019 (not freely available afaik) apparently clarifies in section 14 and Appendix D that if an interval specifies a non-existing data then you back up to the last available day. I take this to mean that R/2021-01-31P1M specifies the intervals 2021-01-31P1M, 2021-02-28P1M, 2021-03-31P1M etc.
