[MapServer-users] wms time validation of time parameter against timeextent gives unexpected results

Does WMS 1.1 behave the same? I suppose it comes down to how 2022 is
interpreted as part of a range, I would have expected it would mean any
date in that year. Sounds like it's behaving like strictly less than
2022-01-01. What happens if you set the range using full dates, so
something like: 20050101/20221231?
