[Pkg-javascript-devel] Bug#981812: nodejs: wrong timezone offset

[Andrey Nikitin]

Package: nodejs
Version: 12.20.1~dfsg-3
Severity: normal

Hi.

Since "Dec 27 2020" TZ Europe/Volgograd = Europe/Moscow,
with +03h offset.

But nodejs use old (now wrong) +04h offset.

$ env TZ="Europe/Moscow" nodejs -e 'console.log((new Date().getTimezoneOffset())/60)'
-3
$ nodejs -e 'console.log((new Date().getTimezoneOffset())/60)' 
-4
$ env TZ="Europe/Volgograd" nodejs -e 'console.log((new Date().getTimezoneOffset())/60)'
-4

$ zdump -c 2020,2021 -V /usr/share/zoneinfo/Europe/Volgograd
/usr/share/zoneinfo/Europe/Volgograd  Sat Dec 26 21:59:59 2020 UT = Sun Dec 27 01:59:59 2020 +04 isdst=0 gmtoff=14400
/usr/share/zoneinfo/Europe/Volgograd  Sat Dec 26 22:00:00 2020 UT = Sun Dec 27 01:00:00 2020 +03 isdst=0 gmtoff=10800

$ date +"%z (%Z)"
+0300 (+03)

$ strace nodejs -e 'console.log((new Date().getTimezoneOffset())/60)' 2>&1 | grep zone 
stat("/usr/share/zoneinfo-icu/44/le/zoneinfo64.res", 0x7ffea7585330) = -1 ENOENT (Нет такого файла или каталога)
readlink("/etc/localtime", "../usr/share/zoneinfo/Europe/Vol"..., 4095) = 38
stat("/usr/share/zoneinfo-icu/44/le/timezoneTypes.res", 0x7ffea7583570) = -1 ENOENT (Нет такого файла или каталога)
