Why does JS (in Chrome) and system show different timezones?

Question

ubuntu

In the console I write

var d = new Date()
var n = d.getTimezoneOffset();

'n' returns the difference between the current zone and UTC:
0
On a system (Ubuntu), the date command returns
Thu. Feb. 20 12:13:12 EUROPE 2014
I.e. the zone is set to EUROPE/MOSCOW
How so? Where does JS think (in chrome) is it in UTC?

Answer 1

dpkg-reconfigure tzdata
select Moscow
TZ='Europe/Moscow'; export TZ
restart chrome
