This error message in the console resulted from directly passing Central Time (US & Canada) as the value for time_zone in a moment.tz(date, time_zone) call.

Instead of Central Time (US & Canada), the correct value to be passed here is America/Chicago - which is in line with the zone object name property that momentjs uses for uniquely identifying the timezone.

Central Time (US & Canada) is the friendlier name for timezone used by rails.

Got around the issue by passing time_zone.tzinfo.identifier instead of just time_zone.

```ruby

time_zone => (GMT-06:00) Central Time (US & Canada)

time_zone.tzinfo.identifier => “America/Chicago”
