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.
It is linked to Windows Control Panel, changing it to different
settings I have in the same Cygwin session :
$ unset TZ
$ date +'%Y-%m-%d %H:%M:%S %z (%Z)'
2017-05-03 17:51:52 +0200 (WEDT)
$ date +'%Y-%m-%d %H:%M:%S %z (%Z)'
2017-05-03 18:53:26 +0300 (TST)
$ date +'%Y-%m-%d %H:%M:%S %z (%Z)'
2017-05-03 22:53:46 +0700 (SEAST)
