moment.js - UTC gives wrong date
...
By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.
In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is format...

Deleting an element from an array in PHP
...unset() will keep indexes untouched, which is what you'd expect when using string indexes (array as hashtable), but can be quite surprising when dealing with integer indexed arrays:
$array = array(0, 1, 2, 3);
