I'm not sure why this behaves differently. The now() function calls down to time_now() in libc, and while we do a setenv() when changing ENV, clearly that change is not reaching down to the relevant parts of libc.
In terms of workaround, if you wanted UTC time, then `now(Base.Dates.UTC)` will give you that. For other timezone conversions, you may want to look at the TimeZones package.
