[EAS] FEMA RWT Feed Timse Zone Groupings

[IPAWS]

The IPAWS originated CAP/EAS RWTs are sent using the "All of state" codes with entire states assigned to the time zone that encompasses the largest portion of the state. That was the only way to comply with the Part 11 limit on the number of FIPS codes used in a single message keeping the RWT testing compatible with convertor driven legacy EAS devices.

There is a chart of RWT time zones which may be found at the following URL:
