Why ?, The type setting in edit-text sets the html type values and is not aware of tiddlywiki date formats. You can use them but you will need to work to use this format dates because you can't simply use javascript as you would on a typical html page.
The format used by tiddlywiki is more precise and numeric only. As a result you can test if one is greater than the other to compare which was first/last. The other date formats need further formatting to do any such comparisons. Look for the date picker plugin to select dates in tiddlywiki format. You can use the html format but you will need to translate it to something similar to do any processing on the dates. You can also make a date stamp button for now using the Now macro. Using the view widget, format date and Now macro you can make tiddlywiki dates look like html dates.
