according to my recent )undated) rand mcnally atlas, the time zone boundary
follows Apalachicola R from Lake seminole to the head of an inlet N of Bay
city. The Franklin scounty line detours to the west of this a little south
of sumatra. As the county is mainly swamp as shown in the atlas, i guess the
line was drawn way before White City and the 71 were formed? The zone line
goes through White City it seems to me.
In Australia, Broken hill is on SA time, not NSW time.
Tweed Heads, the southern end of the gold coast is in NSW which has summer
time while none of Qld does, so in summer, this creates some hiccoughs for
getting kids to school, going to work etc.
Apart from Broken Hill, the zones follow state lines.
