Our 1100 UTC transmission to North America still includes a news summary,

Unfortunately, 1100 UTC is in the wee hours of the morning in western
North America. Perhaps you can add an extra morning transmission to
western NAm by getting rid of the 0100 tx to Central NAm, which I've
always viewed as unnecessary because the two time zones are only an hour
apart, as opposed to four hours difference between the Atlantic and
Pacific coasts.

4 hours difference? If it's 6 PM in San Francisco (Pacific Time) it's 9 PM here in
Michigan (Eastern Time). That's 3 hours.

It depends on what he means by 'Atlantic'. It's four hours between the
Atlantic time zone and the Pacific coast, not considering daylight
saving time.

It's quite obvious what he meant! The sentence says '... Atlantic and Pacific coasts'.
Not '...Atlantic time zone and Pacific coast'.

But if one wished to get terribly technical then one could go to Alaska which is on the
Pacific coast and toss in another time zone too!
