date format

[Peter Buyze]

In the Info section of a tiddler there is, among other info, the created date.

The format is yyyymmddhhss+4 more digits. I don't want those last 4 digits. How can I change this setting?

Actually, the format is YYYY0MM0DD0hh0mm0ss0XXX

Thus: Year (4), Month (2), Day (2), Hours (2), Minutes (2), Seconds (2), Milliseconds (3)

(see https://tiddlywiki.com/#DateFormat)

My question to you: why don't you want the last digits?

[Peter Buyze]

Eric, I don't want those last digits because they add absolutely nothing, and they only make reading the date, which lacks dashes, more difficult. I would also like to add dashes.

Thanks for providing the link. How can I get into the ViewWidget, and in there is it just a matter of amending the format?

Peter,

Why would you look in info for the date. It is visible in the tiddler subtitle. Go to tiddler $:/core/ui/ViewTemplate/subtitle. and see how that is done.

Tiddler subtitle is right before your eyes when working with your tiddler.

The values stored in the created and modified fields can be used programmatically to sort tiddlers (e.g., in the filter of a $list widget). While these numbers are not very "readable" by people, they ensure that sorting of tiddlers are accurate.

You can use the $view widget to format these values for display purposes.  For example:

<$view field="modified" format="date" template="YYYY/0MM/0DD 0hh:0mm:0ss" />

enjoy,

Birthe, the date in the subtitle is the modified date. I am interested in the created date.

Eric, sorry for a basic question, but where is the view widget located?

You can do what you want as described in the documentation here: https://tiddlywiki.com/#ViewWidget:ViewWidget%20DateFormat

<$view field='created' format=date template='DD-MM-YYYY'/>

Peter,

That is why some people edit the tiddler $:/core/ui/ViewTemplate/subtitle. You are right modified field is used here, you could use both modified and created field. I have one to the left and one to the right of my subtitle at least in some of my wikies.

The date that is shown in each tiddler's heading comes from $:/core/ui/ViewTemplate/subtitle

which shows the *modified* date, using this line:

<$view field="modified" format="date" template={{$:/language/Tiddler/DateFormat}}/>

If you change the field="..." parameter value to "created", it will show the creation date of the tiddler.  Alternatively, you could ADD an extra $view widget to show both dates... something like this:

created on &nbsp;

<$view field="created" format="date" template={{$:/language/Tiddler/DateFormat}}/>, 

modified on &nbsp;

<$view field="modified" format="date" template={{$:/language/Tiddler/DateFormat}}/>

Note also that the "template" for this $view widget is a reference to the shadow tiddler,  $:/language/Tiddler/DateFormat, which contains:

DDth MMM YYYY at hh12:0mmam

You can edit this shadow to change the  format of the date output to suit your tastes.

The available formatting codes are defined here: https://tiddlywiki.com/#DateFormat

enjoy,

[Peter Buyze]

Eric, Birthe, thank you. I'm going to go for an extra view widget for the created date, so I will use Eric's code for that.

I imagine I have to create a new tiddler and in the text box put Eric's code. But what title should I give the tid, and should I put anything in the tag field?

In other words, if you edit $:/core/ui/ViewTemplate/subtitle, like this:

\whitespace trim
<$reveal type="nomatch" stateTitle=<<folded-state>> text="hide" tag="div" retain="yes" animate="yes">
<div class="tc-subtitle">
<$link to={{!!modifier}} />
M: <$view field="modified" format="date" template={{$:/language/Tiddler/DateFormat}}/> |
C: <$view field="created" format="date" template={{$:/language/Tiddler/DateFormat}}/>
</div>
</$reveal>

Then it will show both the modified and created dates. It's kind of busy though.

When you make modifications to a core tiddler, you should make a note of it, probably in the same TW,

so that when you upgrade you can delete your changes, make the upgrade, and then reinstall.

Otherwise what happens is that after an upgrade and everyone is talking about the exciting new

date field feature, you'll be wondering why you didn't get it. It's easy once you make a change

like this to forget that you ever did it.

Good luck!
