And the results are in! Thank you to everyone who posted answers to our #DoYouFWI Challenge

Congratulations to Brian O’Neill, who took home the prize via Twitter. Brian’s going to get a gift package with some sweet FWI swag. And just in case Brian has no need for sweet FWI swag, we’re throwing in a $100 Visa Gift Card on top. 

Stay tuned for more challenges, trivia, and chances to win! 

So… in case you missed the answer… what the heck does that expression from the challenge actually do? Here’s the expression again: 

{&exp:((ToUnixTime(‘3/16/2016′) – ToUnixTime(date([&now],’d’))) / 60) / 60 / 24|_num(0)} day{&exp:((ToUnixTime(‘3/16/2016′) – ToUnixTime(date([&now],’d’))) / 60) / 60 / 24 > 1 ? ‘s’ : ”} to DSE! 

The expression uses a new function, coming in 5.2.1: ToUnixTime(). Unix Time (also known as Epoch Time) is a standard for converting a date to a number. It is literally the number of seconds since January 1st, 1970 (not counting leap seconds). 

Why is this important? Well, this allows us to convert dates to numbers and run calculations on those numbers. In the case of this expression, we are subtracting the number of seconds from 3/16/2016 to today (using [&now]). We then divide that number of seconds by 60, 60 again, and 24 to give us the number of minutes… then hours… then days until 3/16/2016. 

And the result? A countdown timer to 3/16, which also happens to be the opening day of the Exhibition Hall at DSE (the Digital Signage Expo.) If you’re traveling to Las Vegas for the conference, swing by our booth and say hello! Who knows what goodies you’ll run across…
