Those figures are correct for US locations that are on Daylight Savings
Time. The US east coast is usually considered to be 5 hours behind UTC.

Akchooly, that's true fur Standard Time, but during Daylight Savings
Time Eastern Time is 4 hours behind GMT. Da Central Time Zone where I
am is 5 hours behind GMT during Daylight Savings, and 6 hours behind
during Standard Time.

Mine hoomin duz GMT conversions allllll day long.
