Support JavaScript Back End

I get ReferenceError: h$get_current_timezone_seconds is not defined, presumably due to the following code:

{-# CFILES cbits/HsTime.c #-}
foreign import ccall unsafe "HsTime.h get_current_timezone_seconds"
    get_current_timezone_seconds ::
        CTime -> Ptr CInt -> Ptr CString -> IO CLong

Hmm, does getting the current time even work?

[tysonzero]

Yep getCurrentTime works fine!

Mostly done, just getting the wrong result for the current TimeZone

Fixed current TimeZone.
Done.
