Bug#1076385: tzdata: Wrong time conversion between IST and CEST timezone, using /usr/bin/date.
Package: tzdata
Version: 2024a-0+deb12u1
Severity: normal
Tags: upstream l10n
Package: coreutils
Version: 9.1-1, 9.4-3.1
Hello,
I noticed that thew `date -d ...` utility converts time between EST and
CEST timezone in wrong way. The time is shifted by 1 hour later:
# cat /etc/timezone
Europe/Prague
# date -d '7:00AM EST'
Po 15. července 2024, 14:00:00 CEST
Env. LANG and LC_* does not change result, just not localised:
# date -d '07:00 EST'
Mon Jul 15 14:00:00 CEST 2024
The expected time is 13:00 CEST.
The problem is observed across all available versions of tzdata or
coreutils in actual Debian releases (tzdata 2024a-4 too).
I am not sure, if a bug sits in tzdata or inside the date from
coreutils, so I attached details about coreutils too...
Thank you and have a nice day, Michal Heppler
