};Enhances the native JavaScript Date.parse function to support ISO8601 and Microsoft format dates. Note: ES5 15.9.4.2 states that the string should attempt to be parsed as a an ISO8601 string before falling back to any implementation-specific date parsing. The native Date.parse() doesn’t do this on all browsers, so it needs to be overwritten to force this behavior and ensure consistency.
