Timeline Dates

[Nickjf]

I've just started using TW, so apologies if this is a silly question.
What i want to know is whether I can change the Timeline date so that
it reflects the date something occurred rather than the date I added
it to TW. So can I post a story about man walks on the moon and get
the Timeline to show July 21, 1969. Thanks.

Welcome, Nick!

Don't worry - we're a friendly bunch here, and always glad to help!

That would be possible - but it would involve either using a custom
extended field[1] or modifying the respective tiddlers' modified or
created date.

A ForEachTiddler[2] macro call in combination with tiddler slices[3]
might be a more favorable solution.

For example, you might have a tiddler like this:
|Date|1969-07-20|
Apollo Eagle lands on the lunar surface.
The corresponding ForEachTiddler macro call might look like this:
---------------
<<forEachTiddler
where 'tiddler.tags.contains("tmp")'
sortBy 'getDateSlice(tiddler)'
script 'function getDateSlice(t) {
return store.getTiddlerSlice(t.title, "Date");
}'
write '"|" + getDateSlice(tiddler) + "|"
+ "[[" + tiddler.title + "]]|\n"'
begin '"|!Date|!Tiddler|h\n"'
>>
---------------

That's very helpful. Thanks very much.

I have a couple of probs outstanding, and I hope I'm on the right
lines.

British-style date DD, MM, YYYY, is, I think, something to do with
TW configuration.

I'm a bit confused where to put this config , my best guess being in
the EachTiddlerPlugin?

The second thing is that it works really well (US-date style) in a new
menu .
So I reckon I can dispose of the TW default menu , or at least the
Timeline, by altering the style sheet?

Nice group and excellent contributions. Thanks again.

There is also a StickyDatePlugin which allows you to add a arbitrary
and permanent date to your tiddler.

If you want to change the default date, find in the righthand
Sidebartabs under 'more' the 'ViewTemplate' tiddler, and change the
following line accordingly:

<span macro='view modified date [[DD mmm YY]]'></span>
(created: <span macro='view created date [[DD mmm YY]]'></span>)

This might do the trick.
However, note that this will not create a new,separate tiddler field,
but rather override the existing last-modifed field.
