The <<.def timeline>> [[macro|Macros]] returns a list of tiddlers in reverse chronological order of modification (or some other [[date field|Date Fields]]), grouped by day.

!! Parameters

;limit
: The maximum number of tiddlers to include, defaulting to 100. But if <<.em any>> tiddlers are included for a particular day, <<.em all>> of the other tiddlers for that day will also be included -- even if this exceeds the limit
;format
: A string specifying the desired [[format|DateFormat]], defaulting to `DDth MMM YYYY`
;subfilter
: An optional extra [[filter step|Filter Step]], e.g. `tag[MyTag]`
;dateField
: The name of the date field to use, defaulting to `modified`

The tiddlers are selected by means of a [[filter expression|Filter Expression]], into which the <<.param subfilter>> and <<.param limit>> parameters are spliced as follows:

> `[!is[system]$subfilter$has[modified]!sort[modified]limit[$limit$]eachday[modified]]`
