问题
Today I noticed my cygwin shell is showing the wrong time. It is actually UTC time while it is supposed to be my local time. As soon as I unset the TZ variable it shows the local time.
Here are some commands which show the situation. I am running windows 10. My windows has UTC-5:00 timezone and its time is OK.I do not remember when did it start to be like this but my colleagues computers are fine. Has anyone seen this before ?
$ date

$ date --utc

$ echo $TZ
America/Toronto
$ unset TZ

$ cygcheck.exe -V

As you might already know, Cygwin sets the timezone in this file :
$ tail -1 /etc/profile.d/tzset.sh
test -z "$TZ" && export TZ=$(/usr/bin/tzset)

Thanks to matzeri that pointed out my tzdata, I tried to reinstall tzdata and saw an error about cygintl-8.dll. I searched for that package in Cygwin web site and fount it there: libintl8-0.19.8.1-2 - libintl8: GNU Internationalization runtime library (installed binaries and support files) reinstalled the package and problem is resolved.
