Working dataviewjs script now fails on "striptime"

[workflowsguy]

I have created a script to implement a "freeze/burnout" feature that adds a static list of created files for my daily note ( "Burning out" dataviews #42 )

I verified that the following script worked as intended

<%*
const dv = app.plugins.plugins.dataview.api;
let Date = tp.date.now("YYYY-MM-DD");
console.log('Date', Date)
//let Date = "2024-02-20";
let result = "";
var results = dv.pages().where(page => 
			     			   dv.func.dateformat(dv.func.striptime(page.created), "yyyy-MM-dd") == Date &&
					           page.file.name != Date &&
						   page.file.name != "Files changed"
						  )
						.sort(File => File.file.ctime, "desc");

results.length > 0 ?
    result = "> [!info]- files created today (" + results.length + ")\n" +
        results.map(page => "> - " + dv.fileLink(page.file.path)).join("\n") :
    result = "> [!info]- files created today (0)";
tR += result;
%>

But after I implemented additional parts to add similar functionality for the "changed" and "reviewed" properties, in further tests the above script now fails with

plugin:templater-obsidian:61 Templater Error: Template parsing error, aborting. 
 No implementation of 'striptime' found for arguments: string

I do not understand why it suddenly complains about a "string" argument, as the "created" property was and still is of type "Date & Time" (verified this in Obsidian properties view).

Another interesting question is why do you use striptime at all when applying a date format which removes any time components?

And the way the query is written currently, you need to verify that every file in your vault has a good type on the created field.

Finally, even though Obsidian approves of the date & time field, that doesn't mean that Dataview will approve. One critical difference is seen below:

Obsidian approves of "2024-03-17 22:05:00", which to Dataview will be considered a string. A proper test of date within dataviewjs would rather be to do something like:

(dv.func.typeof(page.created) = "date" && dv.func.dateformat(page.created, "yyyy-MM-dd") == Date)

Potentially depending on how you've set up your vault with templates and date&time insertions you could consider using date(page.created, "yyyy-MM-dd HH:mm:ss") or similar to get the date out of that string. Adjust format to be what you've used in your vault.

Do note that you can enter this date string with a space, and Obsidian treats as a date&time, but if you change using the properties editor it'll also change to become a date&time (with the T inserted) which is what Dataview expects.
