Given the starting time/date and duration, how can I make a server side calculation that determines if an object is "finished", "in progress", or "upcoming"
--Show
--duration: "144"
--startDate: "2015-11-10"
--startTime: "14:00"
--status: "?"
Client-side javascript to determine if the show has started yet:
// if negative, then show hasn't started yet
var time = (-(startdate.getTime() - currentdate.getTime()) / 1000 / 60);
Client-side javascript to determine if the show has finished running yet:
// if negative, then show has finished
var timeLeft = channelDuration - timerStartTime;
