Many of Pacemaker's date/time options use the [[https://en.wikipedia.org/wiki/ISO_8601 | ISO 8601]] format (with extensions). An old pull request fixing a date/timean ISO 8601 parsing bug should be forward-ported, proofed, and tested.
Alternatively, we could reimplement Pacemaker's ISO8601 functions by wrapping GDateTime and handling Pacemaker's extensions.
