@Cory Weiner the simple answer is that any Dates will be created with respect to your NetSuite instance’s locale. For most of North America, that is Pacific time. The better way to handle this is to use a Date & Time library, with timezones, to properly handle date creation with respect to the correct timezone (UTC, your local time, etc.), Moment and js-joda are some good options (moment is fairly popular, but officially deprecated now), but other libraries like date-fns may work too.
