This seems to already be happening. Here's what I see on my Cygwin
system:
$ echo $TZ
America/New_York
$ date +'%Y-%m-%d %H:%M:%S %z (%Z)'
2017-05-03 07:29:03 -0400 (EDT)
$ TZ= date +'%Y-%m-%d %H:%M:%S %z (%Z)'
2017-05-03 11:29:14 +0000 (GMT)
$ unset TZ
$ date +'%Y-%m-%d %H:%M:%S %z (%Z)'

Hmm, but is the last output line because the Windows Control Panel
specifies New York time, or because there is a 'localtime' file
maintained by Cygwin that specifies New York time? I'm guessing the
latter, since that's what glibc does. The former is what Bruno is asking
for.
