As @abusch notes, a date time stamp is in $Created. If you want it exactly like in The Archive, then you want to do a little more. Let’s assume $Created is the date 2018-03-14 at time 21:15:34, so you want a slug of text like 20180314211534
. This code will achieve that, in this case putting the result in attribute ‘MyString’:
$MyString = $Created.format("yM0Dhmms");
But, before copying that into your Tinderbox zettelkasten ask yourself if you are slavishly following the appearance of the technique in a less powerful tool or implementing the concept.
As the presenter at the last meet-up admitted, the ‘style’ of putting this date-time string at the start of note titles is actually working round limitations of the system they use. So, things like nvAlt and The Archive (and a number of other PKMs) don’t have a data file. Instead they can only look at a folder of plain text† files, where one file == one note. That makes it hard to files in date (or reverse date) order, so the date/time slug is added for sorting purposes. Having done that hindsight allows one to imbue all sorts of magic properties to its presence. But, you might well put that same date (with or without time) in the body of the note is form more easily read by eye: in the USA that might be “March 14, 2018’, elsewhere " 14 March 2018”. The point being is the info informative to you as the record user?
Meanwhile, Tinderbox can sort notes in $Modified (or reverse $Modified) order so you don’t need a 12-digit prefix to all your note titles just for sorting.
And so on… When implementing the concept in you TBX, stop to consider what is legacy format constraint. If you replace your horse-and-cart with a truck, does that mean you should never travel faster that the horse could, or carry more load than the horse could pull? So, you can put the reverse-date-time string at the from also all names but it’s not needed in Tinderbox. Beyond that it’s a matter of choice.
The code of the zettelkasten process is thinking about what why you want a note on a topic and making sure you create that clearly one in your system and cross-ref to it as necessary. Tinderbox can do that and you don’t even have to mess around with Markdown’s plodding square-bracket link notation link notation—Tinderbox has richer tools. and cross linking the notes—and Tinderbox sure knows how to link.
So trying to mimic The Archive in Tinderbox is to drive your race car in first great. But it doesn’t stop you using the concentration of thought implicit in the zettelkasten method in your TBX.
Want tags/categories, etc., to enrich your annotation and classification? Tinderbox has $Tags built-in for the unadventurous but you can add as many user attributes as you want.
†. The affordance of faux-styling Markdown in the app doesn’t alter the fact that it is a plain text file with no other (meta)data in it bsiedes the content of the note.
