What were you trying to do that didn't work?

I am using CLI utility `date` to convert time between timezones. And I noticed, that the time conversion from "EST" timezone to CEST is wrong by 1 hour.

Result can be verified for example in Supportshell.

Please provide the package NVR for which bug is seen:

• coreutils-common-8.32-35.el9.x86_64

• tzdata-2024a-1.el9.noarch
  

How reproducible:

Always

Steps to reproduce

1.  execute 

   $ export TZ=CEST
   $ date -d '8:15 EST'
   Mon Jul 15 01:15:00 PM CEST 2024 

1.  Verify result... Correct time is:

   02:15:00 PM

1. Be surprised.

Expected results

Correct time conversion

Actual results

Wrong time conversion
