updates to use time comparisons for start/end dates

Many existing template partials take the current time (build time), cast
it to a string, and compares it with the times from the event data (ex.
start/end times) which are also being re-cast to strings here (twice!).

In order to allow us to use timezones as part of our comparison and not
have the formatting involved in comparisons, use the `time` template
function and directly compare against `now` without typecasting.
