Senate Bill 858 (SB 858) and House Bill 1013 (HB 1013) have passed unanimously through each of their respective committees as of January 24, 2018. These bills seek to permanently move Florida to Daylight Saving Time. SB 858 also proposes unifying the time zones of the Panhandle counties to the rest of the state, moving the ten counties that are within the Central Time Zone (UTC06:00) boundaries to the Eastern Time Zone (UTC05:00). If approved by both houses of the Florida Legislature, the change would need to be approved by the United States Department of Transportation as well as the United States Congress.

Is it true that is all of florida on the same time zone?
no
