bug#37060: bug in date / coreutils

[jensbaltrusch]

Hi,

I believe there is a bug in the date utility.

My system is set to Berlin time, now daylight saving time.

When I put in

  date --date='TZ="Europe/Berlin" now'

I get correctly

  Sat 17 Aug 05:11:18 CEST 2019

However, putting in

  date --date='TZ="America/Los_Angeles" now'

yields

  Sat 17 Aug 14:12:03 CEST 2019

which is nonsense. Also, putting in

  date --date='TZ="Asia/Shanghai" now'

giving

  Fri 16 Aug 23:13:36 CEST 2019

which is definitely wrong, as I am currently in China where the sun is  
up and shining.



I get from date --version the following:


date (GNU coreutils) 8.23

My system is

Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u1 (2017-02-22)  
x86_64 GNU/Linux


I get the same kind of error using 'today' instead of 'now', or  
'tomorrow', '1 hour ago', etc.

In case you need further information, please do not hesitate to contact me.

Best,
