MVC DisplayTemplate view and related javascript code to help with converting UTC stored in database to users local time via JS in the browser

LocalizeUtcDate.cshtml

@using SPRI.WebsiteUtilities
@model DateTime
@*
    Note: only meant to serve timezone conversions in the USA and maybe NA and SA.
    Gives you a label with the date formatted to ISO 8601 format, javascript will understand this and be able to convert for display.
    Adds a class that js looks for when converting stuff.
