[julia-users] Why does setting ENV["TZ"] in the REPL behave differently?

[Josef Sachs]

Works as expected with `julia -e`, but the environment variable
does not seem to be respected when set in the REPL.  Can someone
explain the reason, and possibly provide a workaround?

$ TZ=UTC julia -e 'println(now())'
2015-11-01T16:02:37
$ julia -e 'println(now())'
2015-11-01T11:02:42
$ julia -e 'ENV["TZ"] = "UTC"; println(now())'
