This disclosure describes a simple addition to the first-generation in-band on-channel (IBOC) broadcast radio standard tht enbales and simplifies the use of new types of radio-controlled clocks, watches, and other time-keeping devices - including the aural radio receivers themselves. The invention consists of localization data that are added to the broadcast signal to enable receivers to determine their local time zone, the local practice in observing Daylight Saving Time (DST), and whether or not DST is in effect regiionally (nationally), regardless of local practice.
