!!Usage
If you enter {ts} in your tiddler content (without the spaces) it will be replaced with a timestamp when you save the tiddler. Full list of formats:
* {ts} or {t} -> timestamp
* {ds} or {d} -> datestamp
* !ts or !t at start of line -> !!timestamp
* !ds or !d at start of line -> !!datestamp
(I added the extra ! since that's how I like it. Remove it from translations below if required)
!!Notes
* Change the timeFormat and dateFormat below to suit your preference.
* See also http://mptw2.tiddlyspot.com/#AutoCorrectPlugin
* You could invent other translations and add them to the translations array below.
