[00:33:05] <wm-bb>	 <u99of9> At least this US Navy site explains what it does in a detailed note at https://aa.usno.navy.mil/data/JulianDate. The Jet Propulsion Laboratory also switches to Julian while explicitly claiming "Output is always in the Gregorian calendar system" https://ssd.jpl.nasa.gov/tools/jdc/#/jd (re @Al: Maybe, but there is still divergence prior to 1582, where the site uses
[00:33:05] <wm-bb>	 Julian calendar dates.)
[05:53:40] <wm-bb>	 <u99of9> Function Z27665 has potential uses, but making a normal test doesn't seem to work because the interface never lets you add items to the sublists once defined.
[06:53:21] <wm-bb>	 <dvd_ccc27919> I managed to create a testcase, but I had to use Z15142 and I had to do a little edit via JSON (re @u99of9: Function Z27665 has potential uses, but making a normal test doesn't seem to work because the interface never lets you add items...)
[07:04:40] <wm-bb>	 <u99of9> Nice. Thanks. I hadn't realised the usefulness of Z15142 to get around this issue with Z881 (re @dvd_ccc27919: I managed to create a testcase, but I had to use Z15142 and I had to do a little edit via JSON)
[08:53:05] <wm-bb>	 <Al> Fortunately, we can trust the French (I believe) https://ssp.imcce.fr/forms/calendars (re @u99of9: At least this US Navy site explains what it does in a detailed note at https://aa.usno.navy.mil/data/JulianDate.  The Jet Propul...)
[10:27:32] <wm-bb>	 <Al> You can use Z15142 at the higher level to overcome the UI limitations. See Z27682. I’m not sure about the “untyped” limitation, but I’ve created Z27683 to ignore it (since Z23607 untypes the level-1 list, after which we currently don’t care). (re @u99of9: Nice. Thanks. I hadn't realised the usefulness of Z15142 to get around this issue with Z881)
[17:44:58] <wm-bb>	 <Al> Z27669 seems to be a problem (Z504) with Z23883, but I can’t see what it is.
[22:36:35] <wm-bb>	 <Al> (Seems to have resolved itself now.) (re @Al: Z27669 seems to be a problem (Z504) with Z23883, but I can’t see what it is.)
