Get GMT time

[Irving Rabin]

Folks, I am a Julia newcomer. I need to get current time. And now() works just fine. But it returns a local time. And I need GMT time.

I got to documentation. It gave me very nice description:

now() → DateTime

Returns a DateTime corresponding to the user’s system time including the system timezone locale.

now(::Type{UTC}) → DateTime

Returns a DateTime corresponding to the user’s system time as UTC/GMT.

I spent an hour and still couldn't figure out how to call the second method.

Yeah, the second one is a little obscure, because of a couple of issues.

-`UTC` isn't exported from the Dates module, so you'll have to use `Dates.UTC`

-`UTC` is a *type* instead of a instance of a type, (that's what the ::Type{UTC} means)

So the correct way to call this is

now(Dates.UTC)

[Milan Bouchet-Valat]

Just like this:
julia> using Base.Dates

julia> now(UTC)
2015-05-04T18:07:16.464


If you think that's unclear, maybe you could make a pull request to
improve the documentation? Showing how to make the call could be useful.

FWIW, this solution only works with Julia 0.4.
