Improve manual timezone input for create: Handle words like "pacific", autoconvert pst/pdt to the whichever one is currently active Improve confusing time parsing syntax around "at", "on", "in", "for" : Not putting the entire "time" portion of the text after an "at", "on", "in", or "for" can cause the time parser to get a bit confused. This is a bit trickier since it's not trivial to separate out the event title and time in some of these cases, but we can do better.
